As noted, the problem of inadvertent deletion of updated or newly added
Activity bundles may occur in the Journal or in the Home list view (through
the erase action in an extended palette).  The most comprehensive solution
might involve grouping of Journal items [1], but that won't be quick.

A quicker solution may be to recognize the Journal entry type or kind in the
Journal (if that is sufficient) and hide or remove the 'erase' entry action
from the palette in the Journal.  This would force intentional erasure to
occur in the Home list view, where the intent may be clearer.

Alternatively, erasure from the Journal could be disabled for these entries
unless they were in a filtered, Journal view (by their kind, a kind which
currently is not available in the filter list).

grouping.
