#1: checkbox "show hosted maps only"
#2: checkbox "show hosted maps individually"
#3: Improved search, you should be able to specify one or more of the following search parameters:
- search by map name
- search by game name
- search by mode
only checking #1 would result in only showing 1 entry in the list for a given map, although more than 1 are hosted, but not showing maps in the list which arent hosted.
additionally checking #2 would result in showing each instance of a hosted map individually, with a optional game name chosen by the host.
