Nick asked me today if there was a way to just reload the stylesheets without having to reload the whole page, which can be frustrating for AJAX development. I hacked at it for a bit and stuck it on our development environment, then cleaned it up into a bookmarklet. Drag the following link to your toolbar for CSS reloading happiness & superior quality.

Reload CSS

Update: Fixed it to work in Internet Explorer.^* Turns out the original code was doing too much work, adding/removing link elements. The new code simply replaces the href attribute with a randomized value.

javascript:(function() {
    var e = document.getElementsByTagName( "link" );
    for( var i = 0; i < e.length; i++ )
        if( e[ i ].rel.match( /stylesheet/ ) )
            e[ i ].setAttribute( "href", e[ i ].getAttribute( "href" ).replace( /\?_r\=[^&]+|$/, "?_r=" + Math.random() ) );
})();

^* Once. It crashes on the 2nd time, at least in IE6 SP2.
