-The hacking drone as you already pointed out. (I guess you already know, but just in case: you can hack station's storage and make them empty all their cargos into space)
-The shield recharger that helps you in tight situation (like during a pre-boarding assault)
-The shield screener, when launched in group creates a fixed shielding screen which you could use to snipe stuff while being relatively out of harm
-The specialised scanner that helps you to pinpoint the last part of a station to be scanned
-The Novadrone, massive manned torpedo that you guides until the last moment to make that freaking chirurgical strike.
-And my favorite one, the sabotage specialist that allows you to put explosive charges anywhere you want and detonate all of them at safe distance (or not, kamikaze style
)
