Hey, I managed to separate the issues...
First off, the automatic 'mailing lists' are unique as far as I
know. Still, I need some organizing to use it productively.
Getting back to ticket 23 (http://freron.lighthouseapp.com/projects/58672/tickets/23-mailing-l...)
It'd be nice to organize mailing list folders by hand in an easy
fashion. Perhaps by copying/adding them to another folder, whose
subfolders allow to gather mailing lists.
I've got some pretty useless ones - single messages 1 year ago -
and others are spread across some folders (e.g. the
MailMate msgs).
Best, I guess, with some option to restore deleted ones.
I know there are ways to do it with separate custom folders, but
an indicator may be I haven't opened the 'mailing list' folder for
weeks.
