From spambayes@python.org (Nigel Cross):
"""
Please consider this in the future:
- Undo function
I often click the "Recover" button with a selection of
spam, or vice versa, and worry about the effect I have
had on future filtering. Ideally there would be an
Undo function under the SpamBayes menu that would allow
the last action to be reversed (i.e. moving all of the
messages back and reversing the changes made to the
database).
I realize this is not a v1.0 thing, but it would be
good for a later release.
Keep up the good work!
"""
While you can of course undo this (almost) by finding
those messages and clicking the opposite button, an
undo would be simpler. I'm not sure how it would be
triggered, though - an 'undo' button would be a bit of
a waste of space, and I imagine hooking into the Edit
menu's Undo would be extremely difficult.
IAC, opening a feature request since it seems
reasonable, and so can collect dust here <wink>.
