I wish help popup is bound to '?' instead of 'h', which would free up h/l to be used for left/right, completing the h+j+k+l vi experience.

Agreed. I like the idea but the key mappings are "off" by just enough to be jarring ("Don't make me think"), turning me off of using it.

Yeah bit of a missed opportunity since comments are trees, so just having up/down is tedious when ideally you want parent/child and sibling traversal.
