Hey cool project. I had the same problems so I made a similar tool: https://github.com/nikita-skobov/monorepo-git-tools https://github.com/nikita-skobov/monorepo-git-tools The idea is that you can have a set of files/folders in your repository that map to an external repository, and you can contribute updates, and also receive updates back and from the external repository by filtering a temporary branch, and then rebasing the changes. I looked through the documentation and I see you have "Git rebase cannot solve the Not-Forking problem space. Neither can Git submodules." Could you elaborate on why you think git submodules cannot achieve this? My understanding of git submodules is that they offer a solution to this problem of external repository sync, although in a not very convenient way.
