I don't know if this should go here or not (or if it is even feasible), now that we're getting such a nice block system, wouldn't it be more intuitive to get rid of the visible/not visible drop down and replace it with a list of all available modules on one side and then make them visible/non-visible by dragging them to/removing them from "the grid"?
IMHO this would provide a nice overview for building a page and what "building blocks" are available.
Templates and NOT theme permit to override all module template and that's why we don't add the old system. If xoopsers prefer the old one, we can change it of course, but if I remember kris, you say that this parts is unused because we can use override in theme folder, now you have it and you say "where is my templates area ?"
Nicolas, I say this, but we must also remember those who still use the old system for cloning templates via the database, we must find a solution so they can make the transition (script transfer, module, ...) with override theme
