Well my suggestion is probably a bug but oh well
Suggestion: Allow refitting from Fleet Hanger to empty slots on the hud.
Keywords: Refitting
Notes: Currently you unfit modules to both the Cargo and Fleet hanger by dragging them off (If near Depot/Ship Bay) but you can only drag fit to empty slots from the Cargo bay. If you want to fit a module from the Fleet hanger you currently have to open the fitting window to do so.
