I found my original post. Thought it would be under the WindowBlinds tab, but it's somewhere else...
Anyway, there are two simple things I would like to be able to do:
1) Increase the size of the top-right window buttons (close, minimize, etc.) without affecting anything else, like system tray icons.
2) Modify the color of inactive windows to create more distinction between active and inactive windows.
It does not seem to be possible to do this from Windows when anything other than the classic theme is applied.
I downloaded "free" versions of WindowBlinds and SkinStudio. Tried to modify the buttons and move them slightly, which rendered them useless in actual windows. I tried to modify the inactive toolbar color and quickly wound up with everything in all windows looking purple. So, I gave up, uninstalled everything, and decided to be happy with the way things are.
At any rate, thanks for the advice!
