compile list of html5 features jquery is using under the hood

• jQuery and HTML5 elements being handled correctly http://bugs.jquery.com/ticket/6485
• CSS3 style manipulation, vendor prefixes (cssHooks mayhem)
  • maybe finally build an abstraction around manipulating rules? see jQuery.rule woot
• mobile device features
  • gesture support (wrap different APIs)
  • accelerometer (DeviceOrientation API)
  • geolocation
• performance
  • buffered jQuery
  • elem.classList, matchesSelector, etc?
  • use WebWorkers?
• animation fidelity
  • animation via transitions
    • http://playground.benbarnett.net/jquery-animate-enhanced/ see also what Louis Remi Babe is doing
  • use the correct animation technique based on the properties being animated and warn the user if they try to do multiple non-simultaneous hardware-accelerated animations
  • deal correctly with whether or not the browser supports hardware acceleration
• graphics use
  • WebGL (low priority, given the difficulty)
  • Canvas wrapper (Raphael, Processing, what else?)
• offline capability
  • jQuery offline (currrently uses an alternate retrieveJSON... maybe there's a sane way to duck-punch the getJSON API?)
  • Wrap cache manifest events to make it easy to let the user know that a new version of the application is available. Maybe even create an API to manage "app versions"
• effective use of storage
  • compression to make maximal use of the storage available
  • sanely handle out of storage errors
  • wrap localStorage, SQL storage, and IndexedDB
  • wrap IE storage?
• positioning via transform translate()
  • see SproutCore's wantsAcceleratedLayer
• better APIs
  • history.pushState, Workers, websockets
  • ajax() should support all that XHR2 shit (what new features are helpful?)
• database whatever
  • basically Lawnchair

there is also an etherpad with some more stuff...
