Mockup is not ready yet but here should be really big popup box with a catalogue of extra content (maps/mods/skins etc) like google play / app store.

Key features in my opinion is the ability to quickly and easily download/install. The best scenario is Click -> Progress bar -> proposal of quick start to check/play when installed/downloaded

Here in my opinion should be also the section for content creators to add/manage stuff. The content creators should have the possibility to update their packages (for example a map after fixing ome glitches). Updates are distributed to the players via notifications system and stay available through 'help' > 'Check for updates' section

Popups for this section's are not ready, but here some explanations of my vision:

• Ladders: list of ladders, rankings, join a ladder, challenge a player
• Championships: List of championships (with info, dates, rules etc), possibility to view the tournament grid and sign up to upcoming championship
• Events: The full list of community events (top matches, news from Epic, meetings, upcoming updates etc) filtered by tags. Here the user can subscribe to notifications on some event.
• Clans: list of clans, create a new clan, join to a clan, clan details (members, logo, website, tropheys etc), send an invitation for player to join, ask for permission to join the clan
• Demos: Easy access to the recorded demos + maybe the possibility to watch demos from other's (popular demos)
• People: Add a friend, list of friends with the posibility to start a chat with one of them
• Stats: Statistics table as always. On the other hand stats can be moved to a 'People' section. Then the data will be available on the player page (like in social networks)

Popup for help are also not ready yet. Some thoughts:

• Game tutorial: like in UT99, step-by-step in-game instructions to the newbies.
• Free Video on Demand: community-generated videos (tricks, tactics, map overviews, recorded streams, video reports on past events etc). Players can add video hosted on popular video hostings by a link, rate, report old links. Can require premoderation :/
• Check for updates: Would be cool if the game will be able to do self-update, as web browsers do. Would be even cooler if the installed content will be also auto-updateable (author of mutator, for ex. utcomp, has made a new version - all players that installed it received a notifiaction with the proposition to do quick update). That will make the life of players a lot easier and remove the problem of version mismatch
• Resources: List of community resources with the possibility to add new resource and rate the existing ones
