How to display logged user in the panel?

I try to manage/show multiple users connection in the panel. One of the idea is to display the users that are logged (live) in the panel and show a list of connected users. Is it possible ?
Does anyone knows others techniques to manage multiple users logged in the same time and avoid content conflicts ?

Kirby automatically locks content when a user edits a page, so you don’t have to take care of this.

I think, the only way to display all logged in users would be to store each user somewhere on login and remove the user again from the list on logout (will be possible with new user hook from 3.3.0, not currently). But given that Kirby has the content lock feature, you probably don’t need this?
