this is not critical, but would probably best be filed in the "gee, wouldn't it be great" category.
have the option (or the default for that matter) to hide retired tournament characters. it would be especially helpful for those tournies where you go to fighting only tournament characters.
in another vein, on the edit favorites list page, for tournies only, it would be nice to remove the "clan" options and replace with "tournament" ones. so the links would be like "remove non tournament characters" or "add tournament characters i have recently defeated" or "near my score" etc.
