I notice the help view is organized into several sections:
[+] generic bindings
[+] search bindings
[+] main bindings
[+] diff bindings
[+] refs bindings
[+] status bindings
[+] stage bindings
[+] stash bindings
but they are unfolded by default, which leads to a lengthy screen (over 140 lines).

It would be useful to fold up all sections by default except for the section pertaining to the view mode I was just in. For example, if I was viewing refs and I issued the view-help command, then the help view would unfold only the refs bindings and keep all others folded up, unless I intentionally unfold any others.
