Please check back regularly, and upvote if you like any of the ideas I have.

1. After losing in a Researcher Campaign and if you choose to upload your drones to a sandbox world, you cannot use them as-is because they do not have fuel when in Researcher they HAVE fuel, because energy is fuel. The easiest way to do it is to have that buff as an extra upgrade in sandbox. 

2. A tritium-to-fuel generator block that takes in 1 tritium/second and outputs 500 energy per second (or whatever you want).

3. A fuel-to-energy and energy-to-fuel converter. They would convert 5 energy to 4 fuel, and vice-versa. This would be another fix for the above.

4. More than 3 upgrade slots in sandbox, and no cap in stats for the weapons in sandbox (or have that cap be the maximum amount, for example, 100.0 for accuracy for example)

5. Upgrades for everything, for example things with capacity can have it upgraded, Things with regen rate can have it upgraded/downgraded, things with damage can have it changed, and thrusters can have more thrust or less fuel consumption. Afterburners can also have their required speed go down, and even all the way to 0 with all 3 upgrade slots in survival used. Shields can be upgraded by that one buff, but not dynamically. 

6. Make LEDs and sound parts sensor parts. They sense a signal and act appropriately.
7. A survivial mode - Make a drone, and test it like the testing area, only escelate in difficulty as time goes on. Maybe even throw in other brawler drones to make it even harder on the one doing the surviving.
8. Make guns have the same targeting power as VTOLs, including the fixed option that the gun currently has.This will make the programmer captain even easier to use, because now you can just set a gun to target missiontarget, nearest enemy or otherwise.

you now can build factory-VTOL-gun(gun attaches next to VTOL and is fixed to fire through it) and fuel drones or supergenerators on main ship
