I had at the end of the week so I played the game for few hours. These have probably already been reported, but for what is it is worth, here are some observations:

* Selecting a large number of ships to be placed into a group at the later stages of the game (with about 40 or 50 ships in the group), you sometimes have to select all of the ships twice in order to get them into the group. There appears to be a problem in handling clicks, since sometimes it works as expected and other times not.
* Is there a way to remove a group? I have wound up with ships showing up in multiple groups. Normally, when you assign ships to a new group, they are removed from the older group. This could have some advantages though, (call it a feature) since tactically it would allow you to group like ships in small groups, then subgroup them to a large group. Actually --- that probably is a cool feature if it was intended!
* Ships when they make the jump in a group, should travel at the speed of the slowest ship. Otherwise, why put ships into a fleet if they get fed into the meat grinder one at a time?    This could be added as a research item at the higher levels (say around 12 labs).  
* Is there a modifier for the number of star systems that the game will generate at the various levels? It would be nice if there was, since that would allow the user to change the size of the game based on his systems performance.
* Its pretty cool that if you take an enemy planet or asteriod and it has a high likely hood of revolting. What is not so good is that it does it immediately.    The only way I have been able so far to colonize enemy worlds is after the enemy is totally defeated. With no population showing, it is kinda hard to make the case that new colonists would automatically revolt, since this was an enemy who was trying to kill them just a few minutes ago.  
* On generation of asteriods during creation of the game, you sometimes wind up with with asteriods at the end of a chain with no resources. That's cool, but sometimes the game lets me put structures in the asteriod grave well and sometimes it won't.   Does not appear to be consistent in this.

Thanks.
