+Fix the things that are causing the most pain to new users
+----------------------------------------------------------
+1. A new import is tagging all messages as "inbox" -- total pain
+
+Emacs interface (notmuch.el)
+----------------------------
+Add notmuch-bcc and notmuch-cc for setting default Bcc and Cc values,
+(should affect the message-setup-hook).
+
+Switch the notmuch-search view to use "notmuch search --format=json"
+to fix large classes of bugs regarding poorly-escaped output and lame
+regular expressions. (The most recently found, unfixed example is the
+sender's name containing ';' which causes emacs to drop a search
+result.) This may require removing the outer array from the current
+"notmuch search --format=json" results.
+
+Fix '*' to work by simply calling '+' or '-' on a region consisting of
+the entire buffer, (this would avoid one race condition---while still
+leaving other race conditions---but could also potentially make '*' a
+very expensive operation).
+
+Add a global keybinding table for notmuch, and then view-specific
+tables that add to it.
+
+Add a '|' binding from the search view.
+
+Add support for choosing from one of the user's configured email
+addresses for the From line.
+
+Make 'notmuch-show-pipe-message have a private history.
+
+Add support for a delete keybinding that adds a "deleted" tag to the
+current message/thread and make searches not return deleted messages
+by default, (unless the user asks explicitly for deleted messages in
+the search query).
+
+Add keybindings for next/previous thread.
+
+Add support to "mute" a thread (add a "muted" tag and then don't
+display threads in searches by default where any message of the thread
+has the "muted" tag).
+
+Make '=' count from the end rather than from the beginning if more
+than half-way through the buffer.
+
+Fix to automatically wrap long headers (for RFC compliance) before
+sending. This should probably just be fixed in message-mode itself,
+(but perhaps we can have a notmuch-message-mode that layers this on
+top).
+
+Stop hiding the headers so much in the thread-view mode.
+
+Allow opening a message in thread-view mode by clicking on either
+line.
+
+Automatically open a message when navigating to it with N or P.
+
+Change 'a' command in thread-view mode to only archive open messages.
+
+Add a binding to open all closed messages.
+
+Change the 'a'rchive command in the thread view to only archive open
+messages.
+
+Completion
+----------
+Fix bash completion to complete multiple search options (both --first
+and *then* --max-threads), and also complete value for --sort=
+(oldest-first or newest-first).
+
+notmuch command-line tool
+-------------------------
+Add support to "notmuch search" and "notmuch show" to allow for
+listing of duplicate messages, (distinct filenames with the same
+Message-ID). I'm not sure what the option should be named. Perhaps
+--with-duplicates ?
+
+Add a -0 option to "notmuch search" so that one can safely deal with
+any filename with:
+
+ notmuch search --output=files -0 <terms> | xargs -0 <command>
+
+"notmuch setup" should use realpath() before replacing the
+configuration file. The ensures that the final target file of any
+intermediate symbolic links is what is actually replaced, (rather than
+any symbolic link).
+
+Replace "notmuch reply" with "notmuch compose --reply <search-terms>".
+This would enable a plain "notmuch compose" to be used to construct an
+initial message, (which would then have the properly configured name
+and email address in the From: line. We could also then easily support
+"notmuch compose --from <something>" to support getting at alternate
+email addresses.
+
+Fix the --format=json option to not imply --entire-thread.
+
+Implement "notmuch search --exclude-threads=<search-terms>" to allow
+for excluding muted threads, (and any other negative, thread-based
+filtering that the user wants to do).
+
+Fix "notmuch show" so that the UI doesn't fail to show a thread that
+is visible in a search buffer, but happens to no longer match the
+current search. (Perhaps add a --matching=<secondary-search-terms>
+option (or similar) to "notmuch show".) For now, this is being worked
+around in the emacs interface by noticing that "notmuch show" returns
+nothing and re-rerunning the command without the extra arguments.
+
+Add a "--format" option to "notmuch search", (something printf-like
+for selecting what gets printed).
+
+Give "notmuch restore" some progress indicator.
+
+Fix "notmuch restore" to operate in a single pass much like "notmuch
+dump" does, rather than doing N searches into the database, each
+matching 1/N messages.
+
+Add a "-f <filename>" option to select an alternate configuration
+file.
+
+Allow configuration for filename patterns that should be ignored when
+indexing.
+
+Replace the "notmuch part --part=id" command with "notmuch show
+--part=id", (David Edmondson wants to rewrite some of "notmuch show" to
+provide more MIME-structure information in its output first).
+
+Replace the "notmuch search-tags" command with "notmuch search
+--output=tags".
+
+Fix to avoid this ugly message:
+
+ (process:17197): gmime-CRITICAL **: g_mime_message_get_mime_part: assertion `GMIME_IS_MESSAGE (message)' failed
+ Warning: Not indexing empty mime part.
+
+ This probably means adding a test case to generate that message,
+ filing an upstream bug against GMime, and then silencing the
+ notmuch-generated portion of the warning (so that once GMime is
+ fixed, this is all silent).
+
+Simplify notmuch-reply to simply print the headers (we have the
+original values) rather than calling GMime (which encodes) and adding
+the confusing gmime-filter-headers.c code (which decodes).
+
+notmuch library
+---------------
+Add support for custom flag<->tag mappings. In the notmuch
+configuration file this could be
+
+ [maildir]
+ synchronize_flags = R:replied; D*:deleted; S:~unread;
+
+In the library interface this could be implemented with an array of
+structures to define the mapping (flag character, tag name,
+inverse-sense bit (~ above), and tag-when-any-file-flagged
+vs. tag-when-all-files-flagged (* above)).
+
+Add an interface to accept a "key" and a byte stream, rather than a
+filename.
+
+Provide a sane syntax for date ranges. First, we don't want to require
+both endpoints to be specified. For example it would be nice to be
+able to say things like "since:2009-01-1" or "until:2009-01-1" and
+have the other endpoint be implicit. Second we'd like to support
+relative specifications of time such as "since:'2 months ago'". To do
+any of this we're probably going to need to break down an write our
+own parser for the query string rather than using Xapian's QueryParser
+class.
+
+Make failure to read a file (such as a permissions problem) a warning
+rather than an error (should be similar to the existing warning for a
+non-mail file).
