Personally, I didn't really like moving the subreddits further away in the menus. I mostly just browse them, and now they're kinda hard to reach. To not whine without a solution, I thought you could implement a "pull right" menu to access a scrollable list of subreddits. I mean, similar to the menu seen in the youtube vid of the irc client
