Supercedes #129

Nice @xPaw, it's looking good!
One minor suggestion, could we have channels displayed as is on the following channels: #channel1, #channel2, and #channel3?
It would look even more user-friendly :-)

I like that, much better looking and better handled. 👍

@astorije That's slightly tricky because it uses each loop in the template.

We could either use tricks to deal with that in the template, but yes, not pretty. A better way would be to define a human-readable list helper (along those lines: http://stackoverflow.com/a/18831911/1935861) but definitely not worth holding off this PR. I'll make an additional PR later for this :-)
👍
