I'm looking for a mod that makes the menu more similar to the xbox menu/UI, in that it snaps to the dialogue choices/items in your inventory. I've been using my controller to play morrowind lately (for whatever reason it seems easier to me than the keyboard/mouse combo, even though you get less hotkeys) and it would just make it easier if I could get the mouse to snap to the choices rather than moving it with my controller.

Doesn't exist and not possible without either an engine rewrite or some serious low level code altering. Probably.

The menus are hard-coded. Hrnchamd might be able to change them, but changing the code would be the only way to do something like that.
