If Switch Windows could be torn-off (and showed ALL opened views) to be always visible, and you could control how views were organized - such as grouped by file in a hierarchy, or dragging to different positions the way you can with AutoCAD's tabs, that would be great!
If each view name had a close box next to it, so you could close unneeded views without going to them individually (and waiting for them to draw), that would be good too (sim to IE tabs or the Windows taskbar pullout; so you don't have to close all windows & re-open the ones you still want).

BTW, be careful using Ctrl-Tab: if the views look similar, you could be modifying the wrong view.
