Not exactly sure if this is a bug, or just a feature suggestion/mod compatibility addition, but when using a jetpack and flying over a factory, the door still triggers, and you find yourself flying through the factory. Expected behavior would be for the door to only trigger if you are grounded, and jetpacking to behave like being in a vehicle.
Also, when playing in god mode -- without a body (Sandbox or SE Navigation Satellite) -- it's hard to trigger the door entry because the center of the screen isn't indicated, and movements are often too fast for precisely placing the center. Would be nice to allow double-click, or something like that to trigger entry. If double click isn't possible, maybe an enter button on the GUI that pops up when you click the building.
