Maybe I found a bug. It's my first with StartIsBack, definitely not bad for a software I use since 2013
If I redirect my "Documents" folder on a network mapped drive, instead of "Documents" I see the drive letter in the start menu.
This doesn't happen with the standard start menu.
How to reproduce:
1) Create a network share somewhere on a remote location (ex. "\\192.168\1.11\mydocs").
2) Map the network share on a drive letter (P: -> "\\192.168\1.11\mydocs").
3) Change the user "Documents" folder location to "P:\" (without quotes).
4) Tell Windows not to move documents to the new location.
5) Reboot PC.
Now on start menu you should see "P:\" instead of "Documents".
I attach a screenshot.
