1.Make travel faster, it would be more exciting to have more of a rollercoaster ride effect rather than the slow drift we get.
2.Allow me to travel on my bridge with an image of sector space fling by my viewscreen that tilts as I turn.
3.Access to comms, outfit, etc from bridge while travelling.
4.An option for random mobs that the first ship to make contact has a choice to 'tackle them myself'(solo instance) or 'call for help'(open instance that spawns to number of combatents). If call for help is used everyone in a certain area is sent a 'do you want to join Cpt. X in fighting off the klingon attack' message.
5.Remove the grid and make the planetary and aestoriod images more real rather then the glowing ethereal style they appear in now.
6.Trade ships should give the same price as starbases and possibly more for certain types of item. ie you may randomly run into a cargo ship that requires consoles or commodities say and will pay you more than usual for those say 75% rather than the usual 50% of value, just to add some random bonuses for taking the time to fly to find a certain type of freighter.
