Add pre made trails to the game that are unlocked via rank ups. These could be things like:
A huge thruster with a smoke trail that lasts on screen showing where the player has been
Lasers that are emitted from the ship with a similar effect to the singularity weapon, and with the particle effect of the laser weapons that lasts on screen showing where the player has been.
After reaching a high rank, players could us an editor to make their own trails and even trade them on the community market.
