It would make image and document selection a lot faster in many cases if the document selector dialog would remember the last path a user selected, so the next time they bring up the dialog, the user is focused on the same directory in the tree. Instead of having to drill-down from the root for every single use of the dialog.

At first just remembering the last use for a user (it would need to be per user or it wouldn't make sense) for any use of the dialog across the site would be a big help. Further, I think it would be even more slick if it 'remembered' per section. So, using the document selector dialog in the E-commerce section would have its own 'remembered' path than when using it in in the Content tab, or for a different Tools module etc.

Basically, simulate the way Windows file selection dialog often uses the last used path and is remember per application.
