This is the 5th installment of the wish-list and bug report thread.
This topic is the follow on to the first Wish-list for MATLAB Answer sections and second MATLAB Answers Wish-list #2 (and bug reports). The third started out as New design of the forum - grey on white and the fourth MATLAB Answers Wish-list #4 (and bug reports) is also growing so large it is slow to load and navigate.
Same idea as the previous ones: one wish (or bug report) per answer, so that people can vote their wishes.

In Firefox v67, if you click on the m-file attached to a question, it offers to open it in MATLAB. But if I say to open it in MATLAB, it opens a new instance of MATLAB instead of using the existing, already open instance. Plus to make things worse, it does not even open the m-file at all. It just launches MATLAB with all your old m-files open.

This is not happening for me on Mac.

It does however set the current folder to the temporary folder where the m-file gets downloaded to, however it doesn't go so far as to actually open the file in an editor window.

Has there been any further thought on changing what is considered a compulsory field for users asking a question? Title, body and tags appear to be still the only compulsory ones and some users are too lazy to put something intelligent in the tag field which allows you to type literally anything anyway.
Product is not compulsory and, as discussed previously, Release is locked until you select a product. This was the reason given last time I asked about this:
"With respect to the release drop-down being filtered, we do think this is important as it provides users with a smaller, pre-filtered list that is easier to use."
That was over a year ago and it still makes no more sense now than it did then given the reality. As another quick small sample, from the first page of questions just before I typed this, just 8 questions (excluding a Mathworks Tech Support team question) contained product information other than 'Matlab' (for which no releases would be filtered out anyway) and of those, just 5 contain the release. So not only is release locked until you enter the (optional) product, but it isn't compulsory even when you do enter the product. We're simply talking about a list of release numbers that a user has to select from. Having it almost useless just to make it 'easier to use' by filtering out a few releases is creating a 'solution' to a problem that didn't exist.
The release field seems fundamental to me and trivial to include properly. It clearly isn't working as it currently is because very few people fill in the release field. Surely the purpose of Matlab answers is to allow people to ask questions and get answers to them as smoothly as possible. So making it more difficult for the people answering the questions by not having release information just seems totally counter-intuitive. Obviously having the product compulsory for all questions would be a big help too, though again some users just put totally inappropriate products (Matlab Coder and Matlab compiler seem very popular!).

I disagreed with the reasoning then and I disagree with the reasoning now. Especially with the larger language changes it is important to know the release. Otherwise users with older releases are getting errors or users of newer releases don't take advantage of new syntax options.
  • HG2 in R2014b
  • implicit expansion in R2016b
  • dot indexing of temporary variables in R2019b (the syntax myFunction(data).fieldA is now valid)

It is a nuisance that if I add another product to the list that the release information is discarded.

Guillaume on 26 Sep 2019
You get the same nuisance when you raise a bug through their web interface and it's just as annoying there.
I've suggested before to the developers to allow users to enter just a version number and if no product is select to default to matlab. I do think that version should be a compulsory field (with maybe a Not Applicable option for where it doesn't matter like this answer).
For what it's worth we (the CAB) have had several discussions with Mathworks on how to improve answers.

When we insert a hyperlink into Answers from chain link button tool on the tool ribbon, the focus/cursor is not in the "Display Text" or "Target URL" field. It should be in one of them, preferably the Target URL field because I have a link in the clipboard all ready to be pasted in and I'd like to do that as soon as possible. Save us a step and put the cursor in one of the edit fields.

When I press the icon for insterting a link in Firefox/Windows, I get a greyed out page only, but not any dialog. I have to click in the background and press escape to get control over the page again. Which browser is working better?
Walter Roberson
Walter Roberson on 8 Jul 2019
Jan: Interestingly, I do not encounter that problem on Firefox for Mac.
Guillaume
Guillaume on 8 Jul 2019
On the rare occasion that I do use the dialog, I've not encountered that problem either. Firefox on Windows (various FF versions on various computers with either win7 or win10).

Firefox scrolling issue not fixed. I don't know if this happens in other browsers but if I go to comment or answer, the top of the edit box is off the top of the screen, so if I start typing immediately I can't see what I typed. I need to scroll down. It updates the screen with a nice sized edit box, but the top of it should not be above the viewable area.

Thanks, I thought something was crawling over my screen XD

I just panicked for a moment when I saw the comment with a bug crawling ;)

I'm not experiencing the scrolling off the top of the screen issue anymore. I think I've maybe updated Firefox since then. So maybe it was a Firefox issue that's been fixed. I'm now using Firefox version 68.0. I'll continue to see if the issue arises again.

Whenever a text is edited by mobile [safari browser] , the click produces superfluous three letters " ltr " , which is really frustrating.

I think it is odd how untested this editor feels for mobile. They probably put hours into testing for mobile as well, but as an end-user it doesn't feel that way.

True ;), hope it gets fixed soon as well.

Another nice-to-have feature: being able to move threads between the answer section and comments without having to repost them. One example of when it would be useful to only change the post type: this. In that thread there are 6 answers, each with some comments. I am not going to spend time finding out in what order they should be reposted, but if I could move the comment-answers (and their comments) to the comment section of one answer (or the question), that would solve the issue.
That thread is a relatively extreme example, but the problem of posting a comment in the answer section is a common occurence. I believe it has even been suggested that people should get a warning pop-up that they are about to post an answer to their own question (with the default option being 'post as comment').

Editor support on mobile seems not fully tested. (I'm using Android 9 (Lineage OS), with Chrome as browser and Swiftkey as the keyboard)
This morning I tried editing an answer, but I got the new editor, which meant I couldn't select text and click the code button. When posting a comment I suddenly got the workaround (the old style editor with a preview window).
I tried setting the browser to desktop mode, but then all the admin tools disappeared, so I couldn't edit the answer anymore.

The old style editor can be used for new content and for editing content that was created before the new style editor was turned on.
Rik
Rik on 8 Jul 2019
Hmm. I can understand the compatibility-issues this would prevent, but it is still something that is waiting for a more optimal solution.
Guillaume
Guillaume on 8 Jul 2019
The current implementation was implemented as a workaround for the fact that the new editor was completely unusable on mobiles. It's certainly not supposed to be like that but until the new editor actually works on mobiles that's what we're stuck with.

Maybe this idea has been suggested before, but maybe it would be good to have a down vote button. I sometimes see answers of questionable quality, where I don't know where to start to explain why it is such a bad idea. I don't think they should be outright deleted, and a flag doesn't really seem the solution either.
Is this something that I will just have to learn to deal with? Or is there some feature that would solve this?
(obviously I will not link to any recent examples, but you could look up some of my embarrassing first answers)

If I recall correctly we decided against downvotes early on, feeling that it would be better to comment or to post better answers (that might include material showing that the alternative would not work)

Automatically collapsing code blocks that contain more than 10 lines or so might indeed be a useful thing. I would argue against something like that being user-controlable because than we get the scenario Guillaume is describing.
Image Analyst

It might be used for homework answers where you give a hint first, then the hidden spoiler below it. However I don't see any student who would just take the hint and not reveal the answer hidden by the spoiler button.
Or maybe for riddles/jokes??

If you flag something the thread should get in your activity feed. That way people get notified if they write a comment in a flag. Because this mostly concerns inexperienced users, I doubt they are checking back to see if they get any response.
Of course it should still be possible to unfollow, just like after posting a comment or answer.
