For demos and experiments that use new features that are still behind a Chrome flag, it would be great if the flags page would use IDs, so you could just link to the right position like: chrome://flags/#CSS-Shaders instead of telling people to "enable CSS shaders in flags".
Or maybe even have an API (or automatically) to popup some kind of toolbar at the top so you can enable a flag with just a click of a button. Similar like it's done to access the camera, or notifications. Although maybe just for Canary and not in stable?
The below example could read:html5rocks.com
