Just started playing the game today, the Campaign option. I need more information on fleet movement and control because to so far, I'm so frustrated this function, I'm going to quit playing the game. Most basic mouse commands that work in other strategy games don't seem to work here?

Based on the rest of the user friendly interface, I assume I'm missing some thing.

I'm playing the humans. I have my home planent and one colony.

So,
1) I've figured out how to set Set Points and direct ships there. So far I can only establish 3 points.
2) can't figure out how to get ships unstacked, and/or a) re-direct certain groups of ship w/in the fleet, o I can send them to other set points, see detailed stats/specs on a ship w/in a stack.

Thanks in advance for your help.
