i would love to see my rating somewhere without starting a game
Suggestions: Low priority
Make the previous move indication way more easily seen.
I usually use the arrows to click through the 3 moves since I last moved but would prefer to be able to see them easily.
@EyeKnows reminded 1 more thing:
8) Highlight legal moves.
(Here I suppose that 6) was suggested by @iparthpandya and 7) by @EyeKnows )
Maybe you could have betting for points!
Like, if red wins, I give you 10 points but if blue upset wins, you give me 40 points.
Or something like that
Hey guys, let's develope an "evaluator", to see which team has an edge in 4playersChess

I wish you could get paired with players near your rating. Like for example: 1800 vs 1700 vs 1750 vs 1850. That's reasonable. I am 1700 and I once got paired up with three 1300s!
Not sure if I even like this idea but putting strongest player opposite weakest player (by rank) as a default.

If you want 4 Player Chess to be improved some way, but it is not very important, write your suggestions here.
1) The players should see how many spectators are there watching their game. Some players will avoid insults if they know there are spectators. Some players will avoid making offers like "give me 5 points and then I'll resign", etc. Not all of them, of course.
2) The Top Games list should be sorted. Either by the average rating of 4 players or by rating of the strongest player.
3) Players should see how many players are waiting to start new games right now. And their rating range. Without the players names.
4) Would be fun to have some sort of betting. Spectators watch top games and make their bets (no money involved): Who will be the 1st, the 2nd, etc. Those who were right get some achievements.
5) "Refresh" button in the Top Games list.
