Converts page links to several popular video sites (including YouTube and Nico Nico Douga) to instead link to an embed page on polsy.org.uk which displays the video centered on a mainly blank page, and resized to a usually more appropriate resolution (ie one matching the resolution of the source flash video, to prevent visual/CPU issues caused by resizing). The sites enabled can be configured from the extension's Options page at chrome://extensions YouTube defaults to off as it's the most intrusive Links on the video sites themselves will never be modified. Version 3 update: - remove obsolete video sites - fix timestamps on youtu.be links
