Many males have slightly impaired color vision, so they are sensitive about layer colors. I am one of those males. Default layer colors are far from perfect. Layer 02 and Layer 03 are blue, so they are difficult to distinguish. I hereby propose different colors of default layers - they are shown in the following screenshot.
I have just found a bug in layer panel display of bold font: the name of the first layer in the following screenshot is “Default (R=0, G=0, B=0),” but layer panel displays this layer name as “Default (R=0. G=0. B=0).”
I mentioned this bug already, but I mention it again because it is very irritating. Every time I open a new file, my command prompt disappears because I do not keep it on top of the Rhino window.
I cannot use the mouse wheel to cycle through toolbar groups because I do not keep the command prompt on top of the Rhino window.
