* Teach @git mv@ to not only move the gitlink and the work tree but also update core.worktree and the gitfile
* Let @am@, @bisect@, @checkout@, @checkout-index@, @cherry-pick@, @merge@, @pull@, @read-tree@, @rebase@, @reset@ & @stash@ work recursively on submodules (in progress)
+* Add functionality to move the .git directory of a submodule into the .git/modules directory of the superproject (either by adding a new @git submodule@ command or by providing a script in contrib/)
+* Add an option to @git submodule add@ to move the .git directory of a local repository to be added as submodule into the .git/modules directory of the superproject
* Teach @grep@ the @--recursive@ option
* Add means to specify which submodules shall be populated on clone (which I'd like to implement by teaching @git fetch@ to create submodule repos in .git/modules, recursive checkout will then do the rest)
* Showing that a submodule has a HEAD not on any branch in @git status@
* @gitk@: Add popup menu for submodules to see the detailed history of changes
* Teach @git prune@ the @--recurse-submodules@ option (and maybe honour the same default and options @git fetch@ uses)
* Better support for displaying merge conflicts of submodules
+* Make the @git submodule@ script run in non top-level directories too
* @git gui@: Add submodule menu for adding and fetching submodules
* @git status@ should call @git diff --submodule --ignore-submodules=dirty@ instead of @git submodule summary@ for providing a submodule summary when configured to do so.
-* Add an "always-tip" mode
* Other commands that could benefit from a @--recurse-submodules@ option: @archive@, @branch@, @clean@, @commit@, @revert@, @tag@.
* In the long run, git-submodule.sh should be converted to a rather simple wrapper script around core Git functionality, as more and more of that is implemented in the git core.
