Category Reordering UX could be simpler

I for one certainly think so, yes. I was never suggesting that we should remove it in the first place. There’s ample space for both UI solutions in this case, and they both have merit.

One thing we should look into is the possibility of (maybe automatically) turning off drag and drop in massive lists. I know for a fact that WordPress ran into serious performance issues with large (100+ items) menus because of their drag&drop system. Although (1) that issue could have since been resolved and (2) as a SPA we probably have a better foundation for this type of feature.
