Keyboard navigation inconsistent

Bug 1:
Treeview enabled
Select a folder in tree view, press Ctrl+x navigate to another folder and press Ctrl+v
Crash!

Bug 5:
Still Treeview...
Links to folders are not displayed in Tree view... however this might not be a bug, just a security measure to not allow recursive folders. (could however be resolved I think)

Bug(?) 6:
Treeview doesn't work in the "World" area - maybe enable it for all elements that you have in your Cache?
It would surely be helpful to quickly switch to other folders from a user/group that you're not currently in or who is your friend.
