Steps to reproduce the problem:
1. Add a folder to the workspace 
2. Try and map it
3. What is the folder? I have no idea :)

What is the expected behavior?
I expect to see both an abbreviated file source - but maybe a smaller sized full path variant underneath it.

It would also be good to be able to rename the mappings in the Sources panel too :)

What went wrong?
If I add multiple project folders and try and map them I dont actually know which one is which as the mapping dialog only tells me the last folder and filename...

Did this work before? No
