+2. Allow an easy way to get tags from directory names (if the user has them)
+
+Emacs interface (notmuch.el)
+----------------------------
+Enhance '+' and '-' in the search view to operate on an entire region
+if set.
+
+Fix '*' to work by simply calling '+' or '-' on a region consisting of
+the entire buffer.
+
+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 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).
+
+Fix i-search to open up invisible citations as necessary.
+
+Emacs saved-search interface
+----------------------------
+Here's a proposal Carl wrote (id:87einafy4u.fsf@yoom.home.cworth.org):
+
+ So what I'm imagining for the default notmuch view is something like
+ this:
+
+ Welcome to notmuch.
+
+ Notmuch search: _________________________________________
+
+ Saved searches:
+
+ 55,342 All messages
+ 22 Inbox
+
+ Recent searches:
+
+ 1 from:"someone special" and tag:unread
+ 34 tag:notmuch and tag:todo
+
+ Click (or press Enter) on any search to see the results.
+ Right-click (or press Space) on any recent search to save it.
+
+ So the "saved searches" portion of the view is basically just what
+ notmuch-folder displays now. Above that there's an obvious place to
+ start a new search, (in a slightly more "web-browser-like" way than the
+ typical mini-buffer approach).
+
+ All recent searches appear in the list at the bottom automatically, and
+ there's the documented mechanism for saving a search, (giving it a name
+ and having it appear above).
+
+Portability
+-----------
+Fix configure script to test each compiler warning we want to use.
+
+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
+-------------------------
+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.
+
+Teach "notmuch search" to return many different kinds of results. Some
+ideas:
+
+ notmuch search --output=threads # Default if no --output is given
+ notmuch search --output=messages
+ notmuch search --output=tags
+ notmuch search --output=addresses
+ notmuch search --output=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.
+
+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.
+
+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 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).
+
+Actually compile and install a libnotmuch shared library.
