Posting this here following dicussion on IRC:
It would be nice to configure what is shown on the review screen, including order and help text. This would require a config entry that is either a list of lists or a map. Thus this ticket is pending until change to toml config.
I think we can safely say toml is not going tk happen any time soon. On the other hand, this could be achieved by a similar config setup as the new index-format.
I could also imagine this as an external file, like the notmuch query maps or the folder maps.
