yes.

With my recent changes, it should now be possible to do this.

This is what I have done - I have moved the search flags into the search
criteria.  Please test and check for smoke, etc.

This was talked about long ago but isn't easily done - how do you "lump"
queries together?  For example, how do I specify that I want (A AND B) OR
(C AND D) - the result must contain A/B pairs or C/D pairs - not (A AND B
OR C) AND D - the result must contain D and must contain either A/B pair or
C.  In other words, nobody has come up with an elegant way of making the UI
handle 'parentheses' so, thus, the reason we have either all AND or all OR
searches.

This has been fixed as a result of the new code (since it pretty much uses
the same code previously used for the search criteria).

I don't understand what this is saying.  There is no "important" IMAP
flag, only a "flagged for followup" flag.
