1. waiting for a long time - fillet, chamfer
2 . better selection (lasso, hotkeys for 1,2,3,4,5: switch modes: blender approach is great 1,2,3 for poly, tab - object mode)
3. ogl improvements: reflections, mb other shaders, lines that are closed together ~ that makes buggy view, mb glass with transparancy
4. Bézier and better curve manipulation - SAI as example
5. Hotkeys: scroll up and down (adjusting radius: as designer i don't need to be precise)
6. scripting : points
7. instances
