I think the big files issue is a problem with _really_ big files. Not with
our users will create and modify.
My only concern with this project is keep it really simple for our users.
The objective of have a git backend is have a versioned
Journal, where you can store all the intermediate steps for a entry.
Other than that, does not have too much sense complicate the interaction
with the user.
The other win would be have a automatic backup in the cloud,
but then we need identity, like in the plugins.
