I agree. I will only buy this program if a facility is introduced to reduce the workarea so a dock (either tabbed or not) doesn't overlap application windows. Unless someone has a better solution?
It would need to support all screen edges, of course.
Oh, and why can't a dock contain application window icons (like the taskbar) /and/ tray icons at the same time? And why don't minimised application windows look a bit more obvious in the dock?
Let me say, however, that the zooming of icons completely floored me when I first installed the trial. That has to be the coolest effect I've seen in quite a while.
