Folder info (size, stats)
In details I'd like to see the number of files and folders inside a chosen folder and it's total size.
It'd be also cool to be able to see details for a number of selected folders combined, so I could check the info for a few folders placed next to each other.

The Windows app is a mystery wondering which folders are being worked on (being uploaded) and how much data in each has been sent / left to go.
