LOL... I didn't even think about Spaces. That's a good idea. I was too busy trying to figure out how the heck to down the window transformations that Expose does; looks like it's done through an internal API... bummer.

There is an "override key", toggle Plexer on/off. Yeah, I need to get the icon difference more clear. Is this not the feature you were thinking of?

I'll try and think of a way to get the "disable key" working. I hadn't thought of doing that... that puts a little wrinkle in my current methodology of doing things.
