Add Possibility to add Collaborators on Memos

[vulovix]

Describe the solution you'd like

It would be great if I could add existing user (by username) as collaborator to the Memo I defined as public. What collaborators can do is that they can simply edit the Memo and add more info to the specific topic.

Type of feature

User Experience (UX)

Additional context

This is useful when I want to create some Travel guide or some other type of shared memo, where I would like to simply declare someone as collaborator so we can both contribute to the Guide/memo we are building.

This would be a great improvement of Memos

I just set up memos as a replacement for evernote and was quite surprised that this was not already possible. I would 100% love to see this feature!!
