Ah, now I think I understand what you mean. Well, this could be eventually the hint I was talking about.
Glad we're on the same page now.
I wouldn't call workspace switcher "expose", it's more a zoom visual effect.
So we would have spread (hover on launcher), expose (click an active launcher) and zoom (click on the switcher). Much easier to discuss the issue when we have a precise terminology!
This is an interesting corner case, thanks for pointing it out, could you tell me some applications which are meant to be working in this way? I guess in this case we could handle it via quick menu, just a thought.
For example, Firefox. My mom used to have a panel launcher that she would use to open new windows (she's old school and not much of a tab person), and ironically she can't use the new launcher for that.
Is this the problem you are trying to solve with your "window spread"?
Well, I think I brought up several cases where having the spread was handier, but that would be the main problem to solve, yes. That was my favourite feature from the task list, and the launcher seems to have lost it.
Cheers,
David.
