This has been requested before (four years ago) and declined at that time.  I would like to ask the developers to reconsider.

I am not asking for an 'undo' for every Evo operation, but it should be reletively simple to keep track of various mail flagging operations that can be sequentially undone -- in particular, 'read', 'delete' and 'junk'.

To be clear, the request is not necessarily to reflag, there are shortcut keys and menu items already in place to do that.  My request is so that user can easily find or backup to a mis-flagged email. Having found a previously flagged email, the user can then revert the flagging in the normal way if they wish.

To give some examples from the Evolution user list:

> Just now I accidentally hit the '.' twice while being distracted.  The
> cursor naturally jumped two messages and it took me a frustratingly long
> time (perhaps 10-20 sec) to go back up the list looking for the message
> I had missed.

> On other occasions, I get zipping along flagging read messages (I could
> easily have 50 at a time) and then realize I should have stopped to read
> an earlier message rather than just breezing by, but I am unable to
> backup easily or accurately.

"I would actually love to have an undo for deletes, similar to what you
describe for "read". I occasionally delete something without intending
to. Even though I can undelete it, I first need to find it ..."

I believe 'undo' should be part of the main Evo program, but if it is felt there is not enough demand, it could first be created as a plugin.  I am not a programmer so I can't be the judge of what would be the simplest.
