There are 3 features that I lack:
1. When selecting an area the size of the selected area is not shown anywhere, just the coordinated of the bottom-right angle. Showing the size of the selection would be much useful.
2. Similar to item 1, the size of the drawn rectangles, circles, etc. shapes is not shown.
I suppose these features would be easy to implement, it just has to be decided where exactly the info should be shown. One option is to toggle bottom-right indicator to size indicator. I have no idea what I could use the bottom-right indicator for, so toggling is just fine for me.
3. A little more tricky, maybe I could take care for this- fixed proportions selection would be much useful. For example a user might need to crop a photo before having it on paper. Or one might like to crop an area for a desktop wallpaper. Such a feature exists in XnView, for example.
And maybe 4- it would be nice if LazPaint could export/ import LRS files.
