Show path of open files in sidebar

I think, this was mentioned before somewhere but couldn't find it anymore.
I work with many open files at once which have the same name and are only differentiated by their path. So the list of open files result in being 5x product.py, complete.py etc..
It would be nice to see the end of the path within the empty space either on the left or on the right side of the filename.

For example on the left:
…api/input/collector/product.py
…ox/restapi/abstract/product.py

For example on the right:
product.py - …api/input/collector/
product.py - …ox/restapi/abstract/

The path should be shown in a lighter/transparent color so that the filename is prominent.

PS I prefer the variant on the right.
