This idea is admittedly a direct rip off of CoC. But I love the festure. Basically we need another tab, either in the guild section or on the leader boards UI. In this tab we could view any guilds we have bookmarked. To bookmark a guild there needs to be the option added when viewing another guilds profile. This would help greatly with keeping up with friendly guilds. Checking on on players progress, visiting in game friends islands when they are in other guilds. Right now if the player isn't a game center or Facebook friend, and if they are not on the leader boards, then you can't really find them. Anyways. This would be great.
