The "other mails from same thread" is still a bit problematic with
virtual folders. From my TODO:

 - virtual: If last message matching INTHREAD rule gets expunged, the rest of
   the thread doesn't go away

First you'll need to create a virtual folder that has all the mails that
you would ever want to see in threads. For example:

virtual/all/dovecot-virtual:
-----
INBOX
Sent
some
other
folders
  all
-----

Then based on that create the virtual mailbox you want:

virtual/newstuff/dovecot-virtual:
-----
virtual/all
  inthread refs or unseen recent
-----
