It was claimed earlier in this thread, that plone only lets you undo the

a problem.  A facility that let you only undo "last" transactions
would be safe.  It would also be useful, at least for single-user
systems.  (Note that definition of "last" gets a little tricky in the
presense of transactional undo.)

I would say that the undo the last transaction would be
useful for all systems, but safe only for systems where all
writing comes from one user.
