Oh, I thought you we proposing not using the object chooser at all?
That's what I understood by "A work-around is to query the datastore
directly and present the entries within your own UI".

I think Bitfrost says that activities that wish to access other
objects from the journal will need to ask for permission to read an
specific object type.  Michael, can you comment on this?

I wonder which are the use cases for activities that wish to prefilter
further by date or other parameters.
