Implement lobby filtering for the list() function

[aglitchman]

I would like to exclude lobbies without players from the list.

Plus, I would like to have the lobbies to be sorted by the date the last peer was connected.

Hey @aglitchman, thanks for the suggestion. We are currently fixing some issue with lobbies and we will put this near the top of our roadmap. 👍🏻

Most of this was implemented in the last releases. Proper documentation is still to come.

In fact, it works great! 💯 I use it with the {"playerCount": {"$gte": 1}} filter to get lobbies with players.
