While likely when we're able to make mods someone will do it anyway, I'd like a minimal UI mode. In the same way as pressing scroll lock will completely kill the UI, I'd like to press a button and have it stripped down to just whatever I tick on a checklist. I.E hp / mp, target bar, buffs / debuffs.

I like to play with the UI off when I can, but without the most basic info, I can only do so much before it becomes dangerous to me or my party xD
