SUMMARY It's currently not possible to make the result of a measurement "stick" as you switch to other tools, making it difficult to use it correctly. Ideally it would behave somewhat like other assistants, creating a real object that can be moved, deleted, etc. STEPS TO REPRODUCE 1. Use measure tool to measure something. 2. Select the brush tool. OBSERVED RESULT Measurement result is gone, can't refer to the result while painting. EXPECTED RESULT Some way to make the result stick while continuing to paint. SOFTWARE/OS VERSIONS Krita 4.2.8, manual backport.
A simple possibility would be to make the results of the latest measurement be noted on the status bar, maybe just to the left of the image size and RAM box. e.g. 530px, 27.5 deg. Maybe on two lines of text. It wouldn't take up much space. I'd like to see the angular measurement be from 0 to 180 for anticlockwise angles and 0 to -179.9 for clockwise angles, where the zero direction is to the right of the intial point.
I can agree that the Measure Tool is a bit not useful at the moment, however, it needs some more design and ideas how to improve it before someone can starting coding on that. Being able to use it like assistants or guides is a really nice idea.
