Scenario: We have a ton of feature branches left over from past projects, also from using source tree gitflow, only the local branch is deleted.
I want to be able to see which of these have been merged into a specified branch (i.e. master), so I can cull the old branches.
This is no benefit to stash from a technical viewpoint, but it improves the usability by reducing the number of branches a developer has to walk through.
We are only just starting to use 'pull requests' to do merges. So the existing functionality to 'delete' on merge does not apply.
Prior to stash, I would simply map a network drive to the remote repo, and use the command line to locate and prune all merged branches.
With stash, I am having to do this one at a time, via SourceTree's User Interface.
