I understand, editing an airport is a very long work, more than anyone can imagine before actually doing it.
WED is a very pleasant software to use, once you are familiar with it. But it takes some reading and some learning time.
If you take a look at the scenery gateway, you will realise that airports are being updated at an increasing pace. And you will also realise the huge amoung of work that is still required.
Note that there is no wish list for improvement, as this work is done on a voluntary basis. I guess reporting this on the scenery gateway would be more efficient, but do not expect a quick correction though.
Laminar Research, as far as I understood, is more focused on developping WED, the sim and its systems. Which is already a huge amount of work.
