Mms proposed updates

These are my proposed updates, mostly reflecting the things that I've been doing without documenting them. Feel free to tear them apart. I'll annotate changes that I think need explanation.
@freerobby For (1), I'm gonna have to disagree with you there. Scrolling is very inexpensive to me and I :heart: space. But that's a personal preference, so we'll see what people think. For (2), I think I can more fully spec the format to get rid of that ambiguity, but I definitely hear you.
