Some features I would like to see for game invitations include ways to use ratings to determine which invitations to display.  For example limit the players that can send invitations to those within certain rating ranges which could be set on a global or game by game basis.  Two ideas come to mind here.  One is to display invitations within a certain range of a players own rating.  'The other is to be able to set the actual ranges like players do when creating games for the waiting area.  It would also be nice to set default actions for invitations.  Examples might include auto accepting invitations until a certain number of total active games is reached.  Auto accepting invitations for some games but not others which would be displayed as normal. Another option would be to limit the total number of games for each game type as desired so that invitations only come for games that a player wants to play more.
It would also be nice to have settings to control what time limits would be displayed or accepted.
The friends list might be enhanced so that players can allow friends to always be able to send invitations regardless of the rating limits.
