I don't think there is a product that does what you need. But it isn't too hard to modify the SCX yourself. OK, creating a fancy editor isn't trivial, but it can be done.
If you are looking for a description of the VCX/SCX file structure, you can check out my book (
Advanced Object Oriented Programming with VFP 6.0 from
Hentzenwerke Publishing). Sorry, don't have this document online (unless you speak German...).
