Other than that I see no obviously wrong things. </div><div><br></div><blockquote type="cite">The widget also saves SketchMorphs as pngs to the Journal by Drag'n droping a Sketch on it or by use of tile scripts. That is quite useful if Etoys is deployed as just a paint activity.</blockquote><div><br></div><div>Nice. There should be visual feedback to indicate dropability. Also, why restrict it to sketch morphs? Also, it should not really "eat" the morph ... feedback like when sending a morph to a buddy would be nice. The new entry should get the current timestamp so it shows on top of the Journal.</div><br><blockquote type="cite">Sound playing is just a hack at the moment. <br> <br>One issue that is slowing the widget down so it's almost unusable with big pictures is that the current player is diplayed as a thumbnail in the Viewer, and that operation takes a looong time. <br></blockquote><div><br></div><div>This should obviously be cached. You can listen to Created, Deleted, and Updated signals on the datastore to know when it is necessary to drop your caches.</div><br><blockquote type="cite">So, comments and suggestions are welcome. <br></blockquote></div><div><br></div><div>Hehe: the singular of "entries" is "entry" ;)</div><div><br></div><div>A morph does not belong in the "Sugar-DBus" category, those are only the compiled proxies.</div><div><br></div><div>Setting the cursor does not work yet.</div><div><br></div><div>And once the basics work right we can think about ideas how to make the interface more "etoy-like". I like the idea of reusing the holder's collection protocol. Maybe we can make it look even more like a holder - holders support showing their contents as thumbnails or text or full morphs, for example. For large Journals we need paging support. And much of the slow operations could be done in a background process.</div><div><br></div><div>But for now: Great! This is going to be really useful.</div><div><br></div><div>Maybe if you upload it somewhere accessible by the XO's web browser you would get more comments?
