Description

This issue is an enhancement request, so that the github package can display paths differently than project relatively. Namely relatively from the currently selected file/folder.

Steps to Reproduce

1. [First Step]
2. [Second Step]

Expected behavior:

a possibility to change path style in the github sidebar.

absolute path
relative to currently selected file path: paths relative to the currently selected file / folder (as in git status)

Actual behavior:

no possibility to change path style in the github sidebar. They're always relative to the project's root folder.
