Well, thanks to xou's post and to my neverending boredom I decided to /alias all the main maps for every mode.

See it here : http://pastebin.com/56dy3Qb5 to paste it in your cfg
Or download it here : http://www.mediafire.com/?eqxoa99n1ujmvt5 to put in your ql folder and just add "exec maps.cfg" in your cfg.

Ok so now instead of /callvote map bloodrun or /callvote map dismembrementeohgodhowthefuckdoyouwriteit you just do /ztn or /hub3dm1 and autocompletion works with custom alias so you don't even have to type hub3aeroq3 entirely.

Some maps have multiple alias, like phrantic is either cpm24 or swq4dm1, courtyard is either ctf10 or w2 and aerowalk is either cpm22 or hub3aeroq3.

I guess at least some people will find it useful.

I couldn't be arsed to do all the brand new maps because I don't even know if they will be really played and they don't have any short name.
