I don't think people love mdx more, I think people are unaware of an alternative. Also people don'T necessarily want to convert their whole script to DCX.

On the other hand, people that start a new script or modify theirs can enjoy a pletora of new material to experiment with which offers possibilities they could simply not achieve with mdx.

One major thing that people seem to appreciate is the Cell Layout Algorithm (CLA) which auto-resizes/positions your controls in the dialog when this one is resized. You don't have to fight anymore with 2000 $calc in your code to make it work, the algorithm does it for you based on a couple simple rules defined at the beginning.
