A small, thing, but would seem to save a bunch of unnecessary mousing & clicking:
When you launch a transport, the default troop load is half capacity (500). Now, I'm a guy, so for me a power tool has only two practical settings: "Off" and "full power." Likewise, it will be rare that I ever send out a transport with less than full capacity of 1,000. But now, each time you launch, you have to mouse on over to the window and click five times on the +100 or else grab the slider and pull it up. Wouldn't it be better to make 1,000 the default, so you only have to click "Launch" 99% of the time? I don't want to have to work so hard invading planetery system ...
