Any sort of styling control: if there's a particular style I want applied to certain portions, I have to recreate it at each use. God help me if I decide to change it halfway through the document.

The cursor will occasionally just go where it pleases.

Revision history (compared to diffing git commits) is incredibly frustrating. Click on a revision, read the whole doc, repeat…
