I want to press a 'Find all remote forks' button inside sourcetree to fetch all remote forks. This would be tremendously helpful for users around the world. please consider as some work for future / perhaps put in backlog.
this script does this > perhaps you can cherry pick some logic.

consider that developers could avoid wasting time redoing work - other developers have already completed in other forks.
