The default behavior of Noscript is that it prevents
javascript from running for ALL websites you visit, unless
you specifically add the site to a "white-list".

Yes-script is the complete opposite. It's default behavior
is to allow javascript on all websites unless you add
specific sites to a "black-list".

I placed 4 options on my Opera toolbar: images blocker, flash
blocker, javascript on/off, and "show as IE/FF/Opera".

Seems simpler, doesn't it?
