I just spent 10 $%#&! minutes going through dozens of tabs and probably 100 clicks to simply make a rail be all one color when shown in the elevation, or any 3D window. This is not how we should be spending our time with this program. I reported this four years ago here. Laszlo Nagy was involved in the discussion as well, so it "should" have made it to R&D.
Please, PLEASE make a single button for the stair, curtain wall and rail tool to turn the "entire" 3D representation of those elements one pen.
Do. This. Now! Fix existing potholes already in road.
