EDIT: I didn't realise there was a tech forum discussion on it, but it missed out tihs vital bit of info, in any case, TF2 players beware! (and this probably needs locking).
HUGGGEEEE game UI.Piccy for those who don't click and read me half heartedly want the compact list back. This is the SMALLEST way of getting the UI width wise (height can go down to 600 or so pixels). You can fit more games I guess into the grid view if you really want though:

I also just realised - the lines are obviously big enough for 2 lines of text yet "Warhammer 40000: Dawn of War 2" is cut off?!
Man...deficiency in design these guys.
Anyway, avoid it, there's not much except screen wasting (chat also has huge buttons wasting space btw, only friends seems to be unaffected) and I'll revert in a day or so I think.
