• It should be possible to favorite certain maps and open more details about the map.
• The map list should be sortable by no finish, no local, best local/pb, karma/rating, the map name, author etc.
• It should be possible for users to search specific map names and authors.
• It should be possible to list all maps of an author.
• There should be a tagging system on the maps, so that maps can be categorized into different tags, and these tags can be searched upon to only show maps with a certain tag.
