Would love to see Bartenders upgraded with barter option like Material Traders for Assets & Data.
Something I think needs to be done is make the current "Engineer Mods" work like in every other modern FPS as attachments that you can freely swap & buy at Pioneer Supplies.
Then you could add actual Engineering in a similar form to ship modules (even inspired by them since you already have the SFX assets there)
Could be nice to have different firemodes too (eg : Aphelion changes from current pulse-like to beam-like at the cost of ammo & recoil)
