1. When I pass the mouse over on the down layer option that I can click, change the color (make a mouseover on layer, orto, gumball, etc... )
In the layer option would better see the same order that the layer box on right and add the option to change material.
When I activate Gumball, would be nice could try by point, vertex, face or object.
Lateral toolbar hide/unhide
A problem when you narrow the command line...
