+Add back full-text indexing, (see last version of
+notmuch-index-message.c in the archives).
+
+Investigate using just a simple hash while constructing threads during
+"notmuch setup", then just writing out to Xapian in one shot at the
+end without haivng to rewrite documents nor look anything up.
+
+Rename notmuch_thread_results_t and notmuch_message_results_t to
+notmuch_threads_t and notmuch_messages_t respectively.
+
+Add a talloc context as the first argument to each command in
+notmuch.c.
+
Write a "notmuch show" that displays a single thread.
Fix to use the *last* Message-ID header if multiple such headers are
encountered, (I noticed this is one thing that kept me from seeing the
same message-ID values as sup).
+
+Audit everything for dealing with out-of-memory (and drop xutil.c).
+
+Write a test suite.
+
+Achieve 100% test coverage with the test suite.
