achieve gmail-like threaded view in the bat! (with categorization by received mail folder)

create virtual folder watching both sent mail and the received folder of choice

add folder, colour group columns

thread by nothing; sort by folder

select all in received folder

thread by references (to avoid grouping similar subjects in sent that have no counterpart in desired received folder); selection is maintained

rightclick > thread > park thread -- all thread members of threads with at least one message (= a message in the desired received folder) selected are parked

thread by nothing, sort by parked status. select all parked and change to colour group representing desired folder.

change filter params to include only colour group members.

thread by reference.
