Wondering around sugarlabs wiki I found the way to save the current state of an activity to the journal here <a href="http://wiki.sugarlabs.org/go/Development_Team/Almanac/sugar.activity.activity">http://wiki.sugarlabs.org/go/Development_Team/Almanac/sugar.activity.activity</a> The physics and x2o activities are based on olpcgames.activity which handles reading/writing files to the journal in a rather strange way. Is olpcgames obsolete? I've found much more documentation for sugar.activity than for olpcgames.activity. Will it be a good idea to port the Physics activity from using olpcgames modules to use the sugar modules? Greetings, Asaf
