Hi Marcus,

Thanks for all the useful enhancement feedback, I plan to look through these
in detail when I prepare for v3 - right now family has to get priority.

My initial thoughts from a quick glance is that these are good points that will improve
the docs and functionality, I also have a long list of ideas myself, but I am a bit
reluctant to put significantly more work into this until I have some guarantee that any of
it will be accepted. Maybe we can save some of it for an update patch later?
