The Steam Cloud manager really should remember the last opened folder.

Having to go back to the last folder every time (since you can't upload more than one file at a time) is a reallll pain! The upload manager window shouldn't close in the first place when you upload, but even if it doesn't save the location locally (so that it only opens the same location in the same session), it would be a huge time saver!

Imo, this is a really simple and crucial feature in terms of time-saving. It should be implemented really soon.
