Feature request: List uncommitted changes and stashes within all repos

[selurvedu]

Similar to gst list, except I mostly need to track uncommitted changes, not unpushed commits. Tracking unpushed commits may be hard for repos with multiple remotes, so I can do that manually.

Listing stashes with an optional parameter would be very nice too. I often save uncommitted changes there and it's easy to forget about them.

This should work either without providing a repo path, so the changes within all repos would be listed, or with a path prefix, so, for example, github.com/x-motemen would only list the changes in repos under github.com/x-motemen/, and github.com would list everything under github.com/ but not under gitlab.com/ or codeberg.org/.

Having a command similar to gst doctor would be nice as well.
