We don't need many words there :-) all we need is

 - A listing of Journals available (by date - the numbers after
'datastore' are epoch seconds IIRC) - if there's only one, skip this
stage...

 - A view that looks a bit like the Journal view... we could show an
'action' that is 'inject into journal' (icon of the activity, arrow,
journal icon?).

In that case, another option is to not have a UI, and just "merge" all
the datastores present, in one go, no more questions asked. As part of
it, files are moved (instead of cp'd).

Not sure how to make the above atomic & safe.
