Been working with it now. And now I understand why it works as is does (my questions 1. and 3. are cleared up.)
I like the beta version. For me it has only one quirk, but the workaround is simple. If I have a 16 step page that I want to loop at a 20 step lenght, I have to copy the page and make a two page cluster. Then it works as I want.
I like it, but the question is if other guys are missing something now.
