I see that in v1.4.0 it tells you how many others are queuing. I'm not sure this a good thing. It's like if you want to join a custom game, you avoid the empty ones and pick whichever looks closest to full.
Now when I see that there are 1-3 people queuing it puts me off. Fact is I pretty much always get a game by the second countdown, often by the first, but I think it creates an impression that you'll be waiting for ages. And if people cancel then eventually it will take ages.
