Wish: add maps collection and users management

[ochurlaud]

First thought: I really love your app.

What I miss is the ability to have a group of people owning a collection of maps.

My usecase would be:

• During a meeting, I take notes on a map and save it in the collection of my team.
• Later on, Teammate 1 wants cleans the map, add colors and fix typos from his/her home/office.
• During a second meeting, which I cannot attend, the map is extended by another teammate.

All this time, noone downloaded anything, we just use the server.

Thx for considering :)
