Click to accelerate on the minimap needs to go. Waste of computer resources and if they want to accelerate it, they should click the map where the ship icon is or use the fleet screen.
The map needs arrows for more maps on a planet. Like north, south, east, and west. Planets are not square. It makes the entire world bigger, more need for things like accelerate, and so forth. Also the forts could be 1 on each east to west map to spread them out also with some bonuses at the poles, including possible shorter travel times. It also could mean north and south pole could be a "Planet Gate" that once an alliance reaches level 3 they open the research to attack and use the "Planet Gate" which could decrease time between planets.
Need to fix map lag
Vary the maps some. Oceans, rivers, oasis, and such on planets have more green than most else. Mountains, mountain ranges, etc... have more minerals. Desert regions have more fuel. Then the coveted areas where all 3 main resources meet and are fought over.
Time between planets needs to be greatly extended. Hence the need for Planet Gates, in which to reduce time between planets, an alliance must hold at least 1 on each planet, which cuts travel time in half. Then StarGates at level 5 to reduce solar system travel times and will have to travel to or near the star for that and needed at 2 stars, which cost greatly in rare resources and costs some B creds to research. The same thing for Galactic Gates, except needs to be level 7 alliance and much more expensive. One of the Galaxies will need you to be a level 10 alliance and to form a team to go and explore, allowing you to land on semi-hostile planet similar to leda, but much stronger ore, pirates, trade routes, and such, which could lead to Alien techs.
