FYI, as of last year, Joplin supports profiles on both Desktop and Android that are exactly that. Though you do have to restart the app to toggle between the two.

By note sharing on mobile, what do you mean? I believe you can share some text from any app to Joplin. And there's also a way to share from Joplin to any other app (from the context menu). Or is it not currently working?
By sharing I mean the notebook sharing feature that is available on desktop but not yet mobile. https://discourse.joplinapp.org/t/share-notebooks-and-collab...
My use case is sharing lists etc (e.g a shopping list, task lists) with my wife who barely ever goes on a desktop computer, and have her be able to share lists with me, update them etc.
Thanks again!
Found: in Australia we call them multigrips and I've got a few!
