I cannot agree more. In my line of work (and in my line of thinking) I am frequently making notes, and frequently needing to re-order them as new information comes in. As of this moment, the only way for to to re-order my lists is to go line-by-line to get them to where they need to be. 
And I think it’d be great if we could change/control the formatting list type (like in word). For example, instead of just:
- Thing
- Thing
- Sub Thing
- Sub Thing 2
We could go:
- Thing
- Thing
And instead of having to manually finagle this, we could set it as the defaulting option
