OT but I have a personal vendetta against roman numerals. Any time they are mixed up in nomenclature they give me pause.
I've had so many battles with roman numerals making other numbering systems confusing/redundant that the only place I ever want them are on fancy watches.
Even for that they are beaten by 24hr digital, but thats not quite as stylish.

You can expand it further, but these are usually enough. Got this one in university back when nobody had a computer with them. It really helps structure the material and get back to it later. Seems a bit too intuitive now with all the auto-formatting but still really helpful.
