</div>I get the impression that you're trying to "port" an existing application<br>
(game) to Sugar by looking for APIs that match those you use on other<br>
platforms. This is NOT going to result in a good user experience.<br>
I highly recommend you spend some time _using_ Sugar (as a user, not a<br>
developer) and getting accustomed to the usual work flows first.</blockquote><div><br></div><div>Is restoring a saved game with an object chooser a bad user experience in sugar?</div><div>What would be a more intuitive experience for someone who have spent more time using Sugar?</div>
<div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Yes, you should treat it as a "random gibberish" (i.e. opaque) string.<br>
Everything else should be derived from the metadata (or the file<br>
contents, as appropriate).<br>
