Is possible to backup local webstorage?

Imagine if you play a videogame on home computer, then go to option, select export save data like json, xml or something like that and send to e-mail or USB pendrive, then you go to office or friend's house, use another pc comes no load game, then go to options, select import save data and you are able to load game.

Also it applies for mobile devices.

Is possible?

Hmm, I doubt it. At least at the moment.

Saving and loading Webstorage to and from JSON is a good idea. It's also pretty much the same format as the Dictionary object so they can probably be made interchangable too (e.g. save Dictionary to Webstorage; load Dictionary from Webstorage). Added to todo list.

Cool, sounds like a useful feature to me. <img src="smileys/smiley20.gif" border="0" align="middle" />

Nice one! It may be useful to play anywhere

it would prolly also be useful for level editors and such
