Please don’t ever change that
I was getting increasingly worried reading this thread that MODx could go the way of all the other CMSs and converge on a folder/page or category/item format simply to appeal to end-end users (by that I mean my clients). As a web developer I use modx because it has the best of both worlds and gives me the flexibility I need to build different sites that behave in different ways.
Btw, the new interface looks great. Both design and functionality have been nicely simplified.
