Regarding your first issue - I'm sorry to hear you had documentation issues.

There should be a huge "Send Feedback" widget at the bottom of every single documentation page:

Did you try using this link on any of the pages that you found unhelpful, or bizarrely organised?

I'd encourage you to use this - as all of this feedback comes through to us via an internal system, and it does get reviewed (although I'm sure you can imagine the volume).

Otherwise feel free to reach out to me if you have specific concerns and feel more comfortable doing it that way, or you're unsure about the response you received. (Although quite frankly, I think the form is best, as that gets tracked, and anybody can jump on it).
