Thanx Christian. Nice shortcut (Alt+Enter) which works fine for a single folder.
However, I use "Alt+Shift+Enter" a lot for seeing the the disk usage for all (visible) folders at a time and your solution does unfortunately not help with this, so it could be really nice (

) if you could integrate this feature in TC at some time, so that it was displayed like one of the methods shown with
Green:
OneDrive: 75.317.248 bytes
Total space: 9.269.423.284 bytes
Foldername 75.317.248 / 9.269.423.284
Foldername 9.269.423.284 (0,8% Sky)
Foldername 75.317.248 (0,8% HD)
Maybe it is not possible to integrate, but I can still hope...
