Fair point about Photoshop. Some like it, I'm not too keen myself. I'd like it to be an option though...that would be nice, please everyone then
As for the restore button, I think it *is* inconsistent as far as itunes is concerned.
You have a playlist view, albeit small...you click it....I expect it to at least stretch to the top of the screen (ala Safari etc), but it doesn't, it switches to 'player' view and vice versa.
It's a plus sign....and a plus sign depicts growth IMO, not a 'switch'.
I think its down to the application developer to decide what it does. Firefox stretches to full screen, but I like browsing full screen TBH, as most websites make the most of it (The ones I use anyway).
I don't mind the default behvaiour for the restore/maximize button in most applications. I think it's just in iTunes it bugs me...although I'm learning to live with it now.
I like the idea of an extra button, that might be nice
