>I noticed the Map button - very nice, but what I meant to ask is whether there is a way to operate upon an entire thread at once, e.g. to save the whole thing to a folder or to download the whole thing in one step (i.e. via browser's Save As File...). Similarly, I would like to be able to "mark" a bunch of messages resulting from a search and operate against them as a unit. A single confirmation message for such multi-message operations wouldn't be a problem, but if I must do this one message at a time it sure would be nice if the confirmation could be optionally turned off.

There isn't any confirmation when doing a search. Can you be more specific on this?

As for the ability to have all the search result messages in one file, we will see what can be done.
