In version 12, "Preferences / Folder Tree / Options: Start Folder Tree to Drives" allows showing only drives in the folder tree panel. In beta 13 this option is gone. Instead, the minimum required is "Desktop" then "This PC" prior to the list of drives.
This wastes space both vertically (the "Desktop" and "This PC" lines), and vertically (because of extra indentations).
Can you put this option back please?
