Fixed icons in Now Playing list after site update. Added icons to Multitap on the front page (icon support on the Multitap page, will be added later). Created update checking feature for Chrome and Firefox which will notify about script updates.
Note: Chrome users please check that you are running Chrome version 13 or newer before installing the latest version of the script. (Wrench menu -> About Google Chrome) If you are not on the latest version, the act of opening the About dialog should trigger the update (on Windows).
