Omninote integration

It coud be awesome to have an integration of omninote

With web interface on nextcloud and desktop client it should be an excellent alternative of evernote.

In my opinion omni note is the better free note app I have ever seen on android

There are two related topics in the project issues:

@jan was already involved in the discussion, @Henni & @LukasReschke are the maintainers of the NC notes app ( Any chances/interest to cooperate?

+1 for this!
