Hi,
Thanks for the ping, yes, I'd still like to contribute, it's just that the
company had some other priorities these weeks, but i'll find some time to
clean things up a bit.
There are some questions still:

   - *accessing*: I didn't yet scan the source to check how to put an icon
   in the toolbar to display the local history panel. I guess the best
   approach will be to make this localhistory thing a plugin, so I can start
   by taking the servicerepo plugin as an example. For the prototype, I
   modified the editor.html and added a transparent div, and the panel shows
   up by clicking on that.
   - *when to create an entry*: currently I check the json source of the
   model every 10 seconds, and if it's changed, I create an entry. Maybe this
   should be extended by somehow grouping these entries. For example, if the
   user keeps editing actively for two minutes, I keep only one entry,
   updating that entry every 10 seconds. But if the editing period is longer
   than two minutes for example, I keep one entry for each two minutes block.
   If the user edits for 30 seconds, then waits two minutes, then edits again,
   two entries will be created again. Something like this might be useful to
   keep the history reasonably small, but still quite useful and real-time.
   - *when entries expire*: entries don't yet expire, so the local storage
   can get full after some time. You can delete all entries at once. I think
   we should add the possibility to delete entries individually, and to
   configure that after a specific time, entries are autmatically deleted. Or
   maybe, for entries older than one hour, we keep entries only in 5 minutes
   granularity, after two hours, every 1 hours, and one entry for each day
   older than 24 hours. Or maybe this is unnecessary for our scope ...

What do you think the best way would be to share the prototype with you?
Well, maybe just emailing the files will be enough for now.
I'll try to clean up the source tonight and send you an initial version, so
that you can take a look and try.

Thanks
Gabor
