The lobby page is clearly in need of a refinement / complete overhaul. It was designed for much lower volume of traffic than Main Lobby is facing now.
Let’s gather up suggestions in this thread.
For starters:
Have the filter for open games enabled by default.
Add filters for red heart / golden heart / unranked games.
Add different ways to sort open games, instead of just putting the one created last on the top. For example, sorting by number of players already joined would work way better than this in most cases.
Add a switch to replace setup layouts with avis of players in the game.
