Planetary Interception Flight Paths: It would be fairly neat if when a move to order was issued the TG would plot a to intercept a planet instead of chasing it.
Automated Empire Supply Task Group: It would be freakishly awesome if the empire could keep itself supplied by player defined needs or production stockpile needs by issuing tanker and cargo ship to a specialized task group. Ideally it would be smart enough to to self maintain in needs of fuel and if it needs jump capable ship to reach destinations. This would allow the player to focus on higher level empire mgm, instead of micromanaging the mineral use. Though the civvies may get smart enough to fill this functionality nicely, and this being an end gaol for them would be awesome as well.
