So you intended to display one version per branch, with intermediate 
versions available from a details view?

Now you point it out I see it. :)
Interesting idea.

Hmm, I'm not sure I understand how this fits with what's said above... 
Is the above for the non-timeline view or do you intend to "split" the 
list and show only the latest version of each branch _per_ _buffer_ 
(buffer def. as in #8)?

To me, it's a very useful feature for debugging and should definitely be 
there. Whether somewhere deep in the Journal or in a separate "Datastore 
Explorer" activity is a separate matter, though.
