for 0.5
-------
_ mark thread as unread should remember the unread messages and mark
  only them as unread, just like gmail
_ bugfix: time zone parsing broken?
_ need a better way to force an address to a particular name,
  for things like evite addresses
_ imap "add all folders on this server" option in sup-add
_ for new message flashes, add new message counts until keypress
_ bugfix: missing sources should be handled better
_ search results: highlight relevant snippets and open to relevant
  portion of thread
_ have "notes" (treated as emails to oneself, never sent) as
  first-class objects.

for 0.4
-------
_ bugfix: pressing S on an email address should search to/from
_ bugfix: thread ordering in thread-index-mode sometimes jumps around with 'M'
_ bugfix in completion: capitalization for contact names
_ imap: cache headers
_ imap: share connection to the same server.
_ dispatch-and-kill version of mark thread as unread in thread-view-mode
_ forward for one or more tagged messages should attach them
_ mbox: don't keep filehandles open, and protect all reads with dotlockfile
_ bugfix: screwing with the headers when editing causes a crash

future
------
_ ldbd support
_ don't use a people.txt; store email addresses directly in the index. too many
  problems with email addresses that occur with multiple names.
_ infix match instead of prefix match for tab completion
_ fix killed threads contributing to unread message count problem (prob. need
  to maintain all killed message ids and our own unread message count for
  inbox).
_ emlx support (some os x thing)
_ tab completion for mid-text cursors
_ bugfix: not horizontal scrolling for ncurses text field entry
_ use trac or something. this file is getting a little silly.
_ saved searches
_ bugfix: sometimes, when one new message comes into an imap folder,
  we don't catch it until a reload. but we do see a message
  indicating they're loaded to inbox (imap only? hard to reproduce.)
_ bugfix: ferret flakiness: just added message but can't find it.
   possibly a message id tokenization issue.
_ bugfix: read before thread-index has finished loading then hides the
  thread?!? wtf. (on jamie) (? still valid ?)
_ bugfix: display field width in index-mode needs to be determined
   per-character rather than per-byte
_ select all, starred, to me, etc
_ undo
_ Net::SMTP support
_ ruby-talk:XXXX detection (via hooks?)
_ more control character support in buffer line editing
_ mboxz, mboxbz
_ swappable keymappings
_ bugfix: when returning from a shelling out, sometime ncurses is
   crazy and refuses to interpret any keystrokes
_ configurable colors
_ better batch deletion (extend to non-mbox sources)
_ annotations on messages
_ pop support
_ toggleble wrapping of text
_ maybe: de-archived messages auto-added to inbox
_ prune old entries from people.txt so that it doesn't grow without
   bound
_ maildir+ssh

maybe
-----
_ split out threading & message chunk parsing to a separate library
_ rangefilter on the initial inbox to only consider the most recent 1000 messages

denied
