Joplin profiles

Hello dear developers of this great app!
Just imagine how cool would be that if you would integrate profiles into Joplin!
The idea is for example to share certain notes with certain people without sharing all personal notes!
The case would be:

  1. I have a Joplin synced with my computer by Syncthing
  2. My wife or lovemate have Joplin synced with her computer using dropbox.
  3. We don't want to share personal/working notes to each other
  4. We want to share common household notes

How cool would be to connect a profile to each other and use Joplin for shopping for example!?
The other way around would be adding separate sync to each notepad...

I guess not only me got to this point at this time however we all can't stop dreaming)
