I think it would very useful to asigne a shortcut to "Open Current Folder as _Root".
I think that "F6" would be a good choice. I made test at home and I like.
Do you agree?
You seem to have CSS turned off.
Please don't fill out this field.
Key F6 is already assigned to switch between side pane and folder view. And also Root operations may be dangerous so it's double dangerous to make them such accessible. Sorry.
