New from zBlueSoftware, LLC is a free utility for modifying airports for FSX called FSX Planner. The program is still in beta and has no formal documentation or an automatic installer, but the program is shaping up to have some exciting capabilities. An overview of the program shows many screens of the various features, such as a taxiway sign wizard, fuel triggers, and the ability to put a background image to aid in placement. There is even a support forum set up at FSDeveloper.com for assistance. This utility sure shows promise so give it a go!
