I think we all, at least once, wanted to be able to just drag a Fuselage Block with a Bomb Bay out of the Parts Window. It would have Settings like Speed, the Angle it opens and Size. It would also be the exact same as a normal Fuselage so you don’t have to make the whole Plane out of multiple Parts so it has no Edges sticking out. This would be very useful, because pretty much every Bomber has a Bomb Bay and it would make Life way easier. It would also make the Bomber way more Part Efficient if you want to add Missiles that extend with AG 1-8. You would only need to add a Piston to extend the Missile, so the Bomb Bay would have multiple Uses even for Fighters. The Part could simply be named Bay or something like that. But that’s just me.
