for my purposes, just adding a tag in square brackets, like [deleted]
and [replied] would be fine.  searching's easy, and i've been known to
use Edit on the acme representation of the mailbox, such as

	Edit ,x/^[0-9].*\n(	.*\n)?/g/\[9fans\]/d

to avoid showing any 9fans messages, for example.

for me, it would be fairly pointless if it wasn't persistent.
i wish [replied] was persistent too.
