You're not going to get a different screen type with the current version of Mach3. So you might as well get the best designer possible to work with the current system. When Brian starts on the next "Mach", hopefully a better system will be in place. (Although I don't think the current system is all
that bad)
As for Flash, there are two big hurdles. One, no documentation. I was going to learn to make a Flash screen a year ago, but with no docs, I just quickly learned how to do regular screens instead. And two, the fact that you need to learn Flash. I can do a regular screen, no problem. But even if I had documentation for Flash Screens, I'm guessing I'd need to spend around 100 additional hours (or more) learning to code in Flash (is it called action script??) I'm sure that the majority of screen designers would run into the same issues. But until some good documentation becomes available, I don't think you'll see any new Flash screens.
