I will be rolling JS-BSC into my latest project, BSPRO (http://sourceforge.net/projects/bspro). I will continue to make it available separately, but you'll need to go to the BSPRO page to download the latest versions.
This version fixes several bugs with the input. Also changed the theme to silver/grey, which looks better than the old "Billiard table" theme IMHO. Also implemented collapsible intro text, to make more room for the score tables, as for some users all the tables did not fit on one browser page, causing the page to jump when a pin was toggled.
