I think that it would be great if we could turn different sensors types on and off individually on ships. For example there is little to no reason to put large resolution actives on ships as they will reveal your position as soon as you turn them on. Lower resolution scanners on the other hand like 1-10 in resolution is more effective as the type of craft they tries to find usually struggle to have passive good enough to detect them before they are themselves detected by the active sensors so there can be a reason to use them and not large resolution scanners that will guarantee to reveal you long before you detect anything with that active sensor.
In addition to this I might also think it is time for an upgrade to how hangars work too... it simply is too easy to deploy just about anything with hangars and rely on them for just about anything. In my opinion hangars simply is too powerful and basically is more like a modular compartment than an actual hangar. It is too easy to use them as a compartment to hold modular vessels, sensor options, weapons and everything is perfectly interchangeable with any size, type and configurations. We have advances and rather intricate mechanics for fuel, supplies and ordnance but hangar operations and types are quite free, too dynamic and effective.
hangars should simply be a module where you add certain abilities such as max docking size, launch/recovery capability, ability to reload ordnance, maintenance of weapon versus say sensor system. It should be much cheaper and less space requirement to have say two bays that accommodate two 500t survey shuttles or four 300t recovery shuttles or servicing 20 300t missile fighter-bombers that need a whole different types of maintenance, space for quick reloading of ordnance and fuel as well as rapid launch and recovery facilities. There could be a difference between serviceable and storage capacity and the ability to operate offensive fighters. A ship might even have several separate hangar facilities that can do different things.
I don't think this has to be very complex, just that different things should have different costs and take up different amounts of space too accommodate. Launching and recovering crafts should no more complex than it is to refuel or rearm a ship in space.
