Thanks for the suggestions. I've added them to the proposal.

@Nicolas_Raoul you're correct. Users who aren't logged in can edit pages, but not upload images. I'm sorry for the mistake.

I think we can try to expand the scope of the project a bit and allow users who aren't logged in to browse Commons and upload images as well. It won't require a very drastic refactoring of the application, since MediaWiki and the APIs support anonymous edits (in a manner of speaking, it attributes it to the IP address of the user, instead).
However, the ContributionsActivity would have to go (for a user who isn't logged in, that is) , since the IP of a mobile user will keep changing.
GitHub issue #1221 talks about this too, though the implementation for the fix described there is quite different.
