Hi
Although I don't mind a little variety on my screen, can some please explain to me why the taskbar, task switcher and application icons sometimes change color from yellow to blue to red to grey? What situation reflects what color?
The icons reflect the mode of the lister - a fairly fundamental part of the way listers work in Opus. I recommend you read up on the concepts of source/destination listers...
Yellow: Source
Red: Destination
Blue: Dual Pane
Grey: Neither source nor Destination
