That would be nice, indeed. Patches welcome.

AFAIK there is already imenu support. Patches for etags support would
be welcome.

Not sure how this would work, but would be nice, indeed.

There's M-x sh-show-shell RET
and M-x sh-send-line-or-region-and-step RET

Support for info-lookup (which would hence be used via C-h S) would be
welcome, indeed. Should be pretty easy to do. Patches welcome.

The same goes the other way: the YAsnippet snippets are made unnecessary
by the skeletons provided. Some people prefer one, others prefer the
other, but fundamentally they're basically the same thing. So, please
tell us what *behavior* (rather than underlying library) you'd like to
see, and maybe you can get that from the provided skeletons.
