Would be nice if we had the ability to drag n drop UI elements ingame, and get their coords for the XML file after/or even edit the xml file its from? To make placement in dev much easier, could enable the mode with a hotkey or so

I had this idea a while ago too, but it requires serialization (which we dont have now) and few other things, generally boils down to idea of moving parsing to mojang codecs which would also allow json/nbt files

I guess the light version that might not need parsing is just moving/logging the coordinates after it got moved
