+2. Allow an easy way to get tags from directory names (if the user has them)
+
+3. Fix Xapian defect #250 so tagging is fast.
+
+Emacs interface (notmuch.el)
+----------------------------
+Make the keybindings help ('?') display the summary of each command's
+documentation, not the function name.
+
+Add a global keybinding table for notmuch, and then view-specific
+tables that add to it.
+
+Add a command to archive all threads in a search view.
+
+Add a '|' binding from the search view.
+
+Add a binding to run a search from notmuch-show-mode.
+
+When a thread has been entirely read, start out by closing all
+messages except those that matched the search terms.
+
+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 messags in
+the search query).
+
+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).
+
+Portability
+-----------
+Fix configure script to test each compiler warning we want to use.
+
+Implement strndup locally (or call talloc_strndup instead).
+
+Implement getline locally, (look at gnulib).
+
+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
+-------------------------
+Teach "notmuch search" to return many different kinds of results. Some
+ideas:
+
+ notmuch search --for threads # Default if no --for is given
+ notmuch search --for messages
+ notmuch search --for tags
+ notmuch search --for addresses
+ notmuch search --for terms
+
+Add a "--format" option to "notmuch search", (something printf-like
+for selecting what gets printed).
+
+Add a "--count-only" (or so?) option to "notmuch search" for returning
+the count of search results.
+
+Give "notmuch restore" some progress indicator. Until we get the
+Xapian bugs fixed that are making this operation slow, we really need
+to let the user know that things are still moving.
+
+Add a "-f <filename>" option to select an alternate configuration
+file.
+
+Fix notmuch.c to call add_timestamp/get_timestamp with path names
+relative to the database path. (Otherwise, moving the database to a
+new directory will result in notmuch creating new timestamp documents
+and leaving stale ones behind.)
+
+Ensure that "notmuch new" is sane if its first, giant indexing session
+gets interrupted, (that is, ensure that any results indexed so far are
+flushed).
+
+Fix notmuch.c to use a DIR prefix for directory timestamps, (the idea
+being that it can then add other non-directory timestamps such as for
+noting how far back in the past mail has been indexed, and whether it
+needs to re-tag messages based on a theoretical "auto-tags"
+configuration file).
+
+Make "notmuch new" notice when a mail directory has gone more than a
+month without receiving new mail and use that to trigger the printing
+of the note that the user might want to mark the directory read-only.
+
+Also make "notmuch new" optionally able to just mark those month-old
+directories read-only on its own. (Could conflict with low-volume
+lists such as announce lists if they are setup to deliver to their own
+maildirs.)
+
+Allow configuration for filename patterns that should be ignored when
+indexing.
+
+notmuch library
+---------------
+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 enpoint be implicit. Second we'de 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).
+
+Add support for files that are moved or deleted (which obviously need
+to be handled differently).
+
+Actually compile and install a libnotmuch shared library.
