I like reddit’s multi–whatever, sorry, no clue about the exact terminology: The ability to group several communities in one view. If this is possible right now I can’t figure out how. Would be really nice if I could have in addition to “Subscribed”, “All” and “local” some dropdown that lets me select my own grouped communities. So that I can create a “Development” group with that shows me posts from general programming, python, linux-dev, another group for some linux new related communities and maybe one for entertainment for programmer humor and Pepper&Carrot ;)
