+"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).
