No, this has already been covered previously.  IMAP servers understand prefix
notation:

 OR ( .. ) ( .. )

... not:

  ( .. ) OR ( .. )

Imapfilter converts the infix notation (what you wrote) to prefix (what gets
sent).

Yes, this is more resources friendly for the server and overall faster.

The format of the configuration changes quite soon.  I think that is much
simpler than the existing one (yet the program gets much more powerful).  I
already did the coding, I am currently doing testing and ironing of the bugs.
