This is a general comment post.
I think it would be great if some examples were provided with every version on the configurations required to achieve certain goals.
I realize that there are enough details so that it would be impractical to have an example of every possible configuration.
But I've been struggling with trying to allow multiple users with MySQL accounts to use phpMyAdmin by logging in remotely.
I've been all over the place for weeks now trying to come up with the solution for it.
The question has been asked 1000 times out on the Internet in a variety of forums.
When responses are given, it's guesses or "this worked for me" (but might not work for anyone else).
In this situation, there are only a few (focused) possibilities - remote login for multiple users being one.
It is my opinion that good sufficiently complete examples and clear tutorials can dramatically increase the quality of a product ... usability.
