Hi,
Thank you for your kind words and the details, it helps me a lot!
I think we can solve the first one quickly for sure:
The first alignment issue looks like only an invisible ‘legend’ element somehow being visible, this custom CSS should get rid off that:
[html].wpdreams_asp_sc form[name=options]>fieldset legend {
display: none !important;
}[/html]
..and then the items should be centered correctly.
The second one is much more problematic. I will get back to you once I find something usable, as soon as I can.
