Improve F-Droid listing

[mueller-ma]

I've seen this app on F-Droid, but it lacks screenshots, changelog and a translatable description there. It's pretty easy for you to add these information. Please have a look at this example or at the F-Droid docs or fastlane docs.
After you have commited these files to your repo and tagged a new version, you need to remove the Description and Summary from the metadata file in the F-Droid Data repo.

Would you like to do that and make a pull request?

Ideally we wouldn't clutter this repository with screenshots since binary files are generally bad in .git. Maybe a submodule.

No sorry, I don't have time for that.

You could submit them to the F-Droid data repo.

Oops, I should have read your issue more carefully, I rushed with my reply :)
