This whole thing is atrocious. We had a brief period of HTML5 stuff being cool and fun, and now Google is doing their best to completely ruin it on Chrome, which has such an undeservedly big market share that web apps have to work around all these asinine restrictions and gotchas. They already ruined some of my one-off pages that play sound because now the user has to click them to start them. Do notification noises even work in Chrome now?
