In the new version 4.1.22 there was the following change to the program:
- Removed redundant Display Properties from the layers list in the left sidebar
Now, I found it was a nice feature since you could assign different properties (color, thickness…) to different polylines, surfaces and objects in general, making them more distinct. Although, there was a problem with saving polyline state because it would reset to default color and thickness every time you would reopen the project. It still does that, by the way.
This is just my feedback regarding the change and I was wondering about other users opinion on the matter.
