Those are good questions, Dale, but perhaps those problems will be in Prolific's court and not Jims. Even the "readme.txt" file has Prolific's info in it, so I would presume they'll have a look at the new one, too.
Dunno.
Yes. My points are that (1) We should be willing to test it, if Prolific desires us to do so, to improve the product and make it better for the users; (2) If we don't help, we get whatever Prolific delivers. Which means we're free to criticize how bad it is.
I have no idea (except posting here) how to even offer. But we did test the 3.0 installer version.
