I couldn't find a suggestion like this so here goes.
I was thinking that in the "My Games" lists or perhaps on the actual game screen with the map you could have a link somewhere which says "Find other games like this".... This link would take you to the game finder results page showing all other games that are the exact same game type and map that you clicked the link from and that are awaiting players.
I know this would be handy for me because I often like to play similar game types to games that I've just completed (or am still active in) and it can be a bit tedious going to the game finder all the time and filling in all the options.
From a coding perspective this should be fairly simple to implement and would actually be useful. I can't really see any downsides to this suggestion.
