Feature proposal/question: basic git branches management with Helm?

I would like to be able to do at least some very basic branch manipulation with Helm. What I think of is a command like 'helm-ls-git-branches'. When run, this command will in usual style display all available branches in a git repo. Default (persistent) action would be to switch to a branch. This can't be a tad bit more involved if there are unstaged changes, so some flags and strategies would have to be customized by user how to deal with those (stash auto or similar). It would be nice if the command also offered an option to delete a branch, and to merge/squash marked branches and to push a marked branch or branches upstream. I was looking around on the webb, but I couldn't find any helm interface for managing branches, and I really miss the option to at least checkout branch from within the Helm interface, and to see a list of branches.

I am not sure if this should be tucked in the same app as helm-ls-git or if it should be a separate app.
