I just want to show you what I was working on lately:

I finished rFilter2 for me. It has now two states of alpha, one for out of combat and one for in combat. The grey vertex is working properly now. I found the function that is capable of making items monochrome.
Furthermore I experimented a bit with the border of actionbuttons. You can do nifty things with it when you colorize different states (out of range, not enough mana etc.)
All screens can be found here:

To make a texture monochrome do:
texture:SetDesaturated(1)
otherwise do:
texture:SetDesaturated(nil)
