Really awesome stuff - great interface, great use of cross-hairs for identifying features.
An enhancement idea:
If I have engineering data traces, it would be great to do calibration in 2 directions and then automatically calculate coordinates of points from the origin.
Great tool! I noticed the measurement displays with only two decimal places. Can you build in an option that allows you to select how many significant digits you wish to display the measurement? Also, is it possible to make an option to display the x and y coordinates of the distance as well?
Thanks for posting this app. It is very helpful!
