Due to the complexity of the numerous Embed systems on the site it was long ago decided that it wasn't worth the effort to include dynamic resizing of an infinite number of embeds. However I really really miss the bigger button, and have taken it upon myself to recreate the effect using greasemonkey a scripting plugin for firefox.

This current release has very limited functionality, meaning it only really has support for youtube videos, and even then only some of them. Furthermore it doesn't work on the front page or any other listing page yet, just individual video pages.

You can download my script here once you have finished installing greasemonkey follow these instructions to get it up and running.

Anyway the way this works is that it basically makes the video embed larger than it is normally. In later versions i will add detection for what your current page size is and scale the videos accordingly, but currently videos are optimized for the 1280 resolution so i suggest setting your preferred size to that width.

I would imagine that there will be lots of bug reports etc so please feel free to report them here.
