hjkl are definitely table stakes for a vim-ish editor, but I also can’t live without 0 and $. Making me move my hand over to find home and end misses the point of hjkl entirely.
My hx doesn't wrap lines, so didn't check `gj` and `gk`.
The only long form text that I ever write is in markdown. I do miss the `gq` command from vim, but in general I just do a single line break after every dot. Markdown ignores a single line break in the middle of a paragraph, so it works out okay. I even found it almost convenient to edit text like that because it's easy to move lines around.
In code documentation (which I do a lot of), I have to manually wrap the lines of course (just like anyone else). That's where I miss `gq` the most. :)
