The SDK is really unintuitive and hard to use, except one wants to spend 10 hours+ on tutorials. It may be that in its current state it gives the most possibilities, but for the world hub editing airports must be easy, otherwise the community output will be diminished. We need something like ADE but integrated into the MSFS SDK and in 3D. Give us a big library of objects and textures, that is easy to navigate and filter, an easy and intuitive way to manipulate existing taxiways and roads, parking spots, vehicle placement, autogen buildings, aprons, runways and lighting without having to create more or less the whole airport from scratch. Intuitive Terraforming and usage of Bing satellite data is also a nust. The cherry on top would be an easy way to manipulate 3rd party sceneries, as many beautiful airports have fundamental flaws when they need to interact with ai traffic.
