Everyone knows the fun of bomb bays, nudging the parts into the right place and then tweaking it, and then you have to make it look pretty. Only to find in the end that you now have 100+ parts used just for a simple bomb bay, and you spent 3 hours on it.
Well, what if we had the option to just simply use an object, such as the hollow fuselage, with a button that says "add door." With this door, you can customize the speed, angle, and size of the door much like you would with a wing (where you drag the control surface to customize its size). And then you can just link it to an AG button.
This would be very efficient and easy for anyone to use, and it would be able to smooth into the rest of your fuselage. You could also use this for landing gear, literal doors, or pretty much anything you want to. I personally think it would be an amazing addition.

I dunno, just a thought I had XD
Any feedback?
