This topic (which was not started by Mathworks) is for features you would like to see for this MATLAB Answers facility.
I suggest one wish per answer, so that people can vote for individual wishes.
What should you post where?
Wishlist threads (#1 #2 #3 #4 #5): bugs and feature requests for Matlab Answers
Frustation threads (#1 #2): frustations about usage and capabilities of Matlab itself
Missing feature threads (#1 #2): features that you whish Matlab would have had
@anyone posting a new thread when the last one gets too large (about 50 answers seems a reasonable limit per thread), please update this list in all last threads. (if you don't have editing privileges, just post a comment asking someone to do the edit)

Perhaps this is implemented already - I didn't ask a question yet: If you select an answer as accepted, can you change the selection afterwards, if a better answer is given?

I've created a userscript that applies MATLAB syntax highlighting using google-code-prettify (it was originally intended for Stack Overflow). Project is hosted on GitHub.
Install userscript directly from the following link: prettify-mathworks-answers.user.js

  • In the list of questions, each question should have a "last updated" date and time, where an update is the addition of an answer or a comment or the editing of any part of it.
One can get the list sorted by most recent update time, but without a time stamp, one has to look at the individual questions all through to determine whether there has been an update since the last time one looked at it.

Include questions you've commented on (but not necessarily "answered") in "my answers". This way you can keep an eye on a question where you're asking for clarification or suchlike discussion.
Note: this would be rendered less important if we had notifications of some kind.

Hah. Makes sense. I ripped off that line from somewhere -- it was describing university politics... I can completely see how the stuff I observed at universities was an affluent society's update to our primal urges to have our political enemies ax-murdered by corrupt government goons (after which you take their mud hut, beads, and lion skin loincloths).

Answer folding.
Say there is a question which has 55 some-odd answers. I keep coming back to look and see if there is anything new, but since the answers move up and down with votes and other mechanisms, it soon gets exhausting. If I had the ability to fold answers I have read before - a choice that would stick between logins - then this process would be much easier.
I would like to be able to fold and unfold answers within a question. Perhaps a little star would appear next to the unfold button if there were new comments since I folded the question.

A very important improvement! It is nearly impossible to find the new answer or comment in a set of 55 answers and 100 comments. It seems like even a comment, which is deleted directly after the creation, changes the oder of the answers. Then it is even absolutely impossible to find the modifications...

The accept button should be further away from Comment on this answer, and it should be possible to undo it - at least for a grace period of a few minutes.

Andrew mentioned as part of a previous suggestion that My Answers should include a search box. The same should also hold true when viewing someone's profile.
Go to my Answers and try to find something specific in there. With over 700 Answers logged already, good luck in finding what you are looking for...
The situation would not be as bad if the existing search box supported a tag for author search (and if author names were unique.)

Adding a button for inserting images. Even though instructions for adding an image can be found in Markup help, more than one user has been unaware that it could be done (including one on this page!).

And store the images on a MathWorks server. The other hosters will delete the images in the near or far future and then the corresponding question will become meaningless.

A way to automatically scroll to the most recent answer/comment/edit. For example, this question has many, many answers and comments. But I don't know where the most recent stuff is. Perhaps there should be a "go to next recent content" button on the page, that takes me to different sections.

The sorting regression is fixed--answers should now display with the accepted answer first, then the remaining answers sorted by number of votes (high-to-low) then date/time asked (least-to-most recent)

Walter mentioned a "Best of Answers" area. A more flexible alternative would be an "Add to my favorites" button, so we can each keep a list of answers that we find really useful.
Of course, we can always bookmark them in our browser, but it would be good to keep them in the same environment as our personal questions and answers.

A "Views" counter for the questions.

Walter Roberson on 9 Feb 2011
When one is being shown a list of Questions, it would be nice if hovering over a question link would show you a brief summary (e.g., first 100-ish characters) of the question statement. This would make it faster for people to take a quick look to see whether the question was interesting, or a quick reminder of exactly which question it was.

  1. More meta info about the contributors: num. of votes given, num. of comments...
  2. Keep the meta info separate from answers/questions: try to load Walter's profile...it takes already a lot of time and if he keeps at this rythm in a year it won't be possible to load it at all...
I'm trying to think of long run stable way to query the site to have a score of the contributors. You can see an attempt in User reputation: post here to get into the list. It already takes 6 minutes to retrieve that info.
In general, it would be nicer if the list of the contributors and the meta info was available at one shot (and basically this is what I'm trying to reproduce)
EDIT
TMW team implemented a page with the metascores: http://www.mathworks.com/matlabcentral/answers/contributors
Please refer to it and congrats to the team!

Somewhere or other in the documentation, we need a note saying plainly that when a Title is edited, the effect is to create a URL which aliases the old one. For example, I had
http:.../4321-j-random-title
and after I renamed it, that continued to be valid in addition to the new name
http:.../4321-john-q-title
This behavior of keeping the old name accessible can be important because URLs may have been created linking to the old name. This is a good feature; documenting it would save people like me from having to worry about such things.

Some way to prevent questions being deleted without a good reason!
I'm getting really annoyed with people whose response to your help is to disappear and take with them both their question and your response to it. It's happened more than once to me, and not necessarily questions where the poster was doing something dumb -- perfectly normal question, valid answer(s), then... floop! It's gone.

We implemented a partial constraint on this behavior in a release on June 27, 2012. You can no longer delete your own question once someone has answered it.
Here's a blog post describing the major changes.

I would like to have a way to see when someone's account was created and how many questions that person deleted (maybe even the names of the questions deleted for those who are editors), this is because I clearly remember having answered several questions from someone but all those questions were deleted and the very same person posted a new question yesterday, I replied and that person exhibited the same old behaviour that triggered my memory, he/she didn't even look at the links I provided and asked something that isn't MATLAB related, I didn't answer the specific question because I would waste my time, this is MATLAB Answers not Control Engineering Answers.

We implemented "no delete if already answered" in a release on June 27, 2012. Click on the "Link" button next to an answer or above a comment.

Many questions get asked again and again. Why? Because people are not searching for previous answers before asking questions.
Stackoverflow suggests some similar questions that have already been asked when people are typing in their questions. It's therefore easy for them to see that the questions already exist.
This system also relies on good questions being voted up, so they appear at the top of the list. I have asked several (dare I say) well-worded questions (and usually answered them well too), with a view to providing a resource for people to refer to. This effort is wasted by the questions and answers receiving no votes, and the fact that people never search for them anyway.
So, TMW please implement question suggestions like Stackoverflow, and regular users please vote for well-worded questions.

  • For the benefit of those of us that like to do some infrastructure maintenance, it would be appreciated if there was a way to select questions that had no tag, or that had no Product . Especially in conjunction with the "next question" button that I proposed, this would make it much easier to step through postings adding appropriate meta information.

I like the idea of checking for relevant answers before posting a new question. As mentioned at [1], neural nets would be one vehicle for accomplishing this; alternatively, consider the following routine, for which x and y could be optimized.
Maintain a database of URL's, keywords, and tags for existing articles, threads, and questions.
For each new question title proposed:
* Define X as the set of all words of length > x from the user's proposed title.
* Search the database for articles/threads/questions whose keywords and tags match y% of the members of X.
* Display "Do any of the following answer your question?"
* Display best matches.
Implementing a quality search procedure now could prevent unnecessary clutter and avoid the difficulty of deciding whose answers to delete should cleanup otherwise potentially become necessary. This would help answerers by politely encouraging common sense questioning practices with which to prevent redundant and unnecessary questions, and users would feel more intelligently assisted and locate answers more quickly.
The dual objectives would be time-efficient search and high-quality user feedback. Search time might be reduced by categorizing questions and searching only within relevant categories. And recommendation quality could be optimized by using a modern optimizer to maximize the recommendation success rate per 100 questions on the 2D search space defined by x and y [2].

I do not like to be tracked by Google-Analytics. In Germany it is currently checked, if this service conflictes with the laws for data protection.
It is obvious that participating in a newsgroup is not very private at all. Nevertheless I see no reason to let Google know my IP, such that they can check if I've opened a browser window for Ebay or Amazon, while I'm posting at MATLAB Answers. Or does anyone needs informations like this: "People who have bought this book have been interested in these questions also: ..."
So my wish is: Disable tracking by Google-Analytics.
