As do I.

Note that an address sort that collates all "mrc" messages together is 
more likely to do the right thing that one that collates by name and has 
to figure out that "Mark Crispin", "Mark R. Crispin", "Crispin, Mark", "M 
Crispin", "Mr. Mark Crispin", "IMAP Support", etc. are all the same.

I also sort by Subject (although more commonly ORDERSUBJECT threading than 
direct SUBJECT sorting) in cases where the thread tree has become so 
complex that it has lost value.  A classic example is when a new thread is 
started by replying to a message in a thread that has little or no 
relationship to the thread.  Think USENET.

Usually for flags I would do a filter rather than a SORT, but it seems 
reasonable to me to add such a thing in the first round of extensions.

Date sorting seems to be pretty common with our users.  Some people who 
prefer their mail "in order" use it instead of sequence order in the 
mailbox (no sort) which tends to be an INTERNALDATE sort.
