How to stop buttons (and everything) being huge
Everything in jQueryUI seems to be designed with a font size of 10pt. On pages with the default (for most browsers) of 12pt, all the jQuery widgets are absolutely huge. It's most noticeable with buttons which become nearly three times the size of a normal button due to a span that is added with lots of padding (and this theme of tiny text with lots of em padding to make buttons normal sized seems to be used on everything). It looks very out of place on the page to have these giant buttons and other inputs next to normal size text.
It would be ideal if I could have the colours and border radius of the theme, but have it the original size the browser would make it.
