If I may ask, under what circumstances would you typically use something like this?
(Only thing I can think of is to clean up a page when printing, or saving <as Web Page, complete>.)
Otherwise I would like some sort of "remove" button (or even shift+click) for already playing media.
(Bookmarklets may work, as well as an extension like
Nuke Anything Enhanced. But at times these are too effective or difficult to get the correct element - especially when a page has multiple streams, often starting all at the same time.)
