+Fix the things that are causing the most pain to new users
+----------------------------------------------------------
+1. A new import is tagging all messages as "inbox" -- total pain
+
+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 hidden components self documenting, such as:
+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 command to archive all threads in a search view.
+
+Add a '|' binding from the search view.
+
+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).
- [24-line citation, press 'c' to display.]
+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).
-Add support to compose a reply to the current messaage.
+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
-------------------------
+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".)
+
+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.
+
+Add documented syntax for searching all threads/messages.
+
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.
-Make "notmuch setup" not index all messages, but only what it can do
-in a reasonable amount of time, (then add "notmuch index" so the user
-can complete the job when convenient).
+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.
Fix notmuch.c to call add_timestamp/get_timestamp with path names
relative to the database path. (Otherwise, moving the database to a
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
---------------
+Index content from citations, please.
+
+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).
+
+Add support for files that are moved or deleted (which obviously need
+to be handled differently).
+
Actually compile and install a libnotmuch shared library.
Fix to use the *last* Message-ID header if multiple such headers are
Add support for the user to specify custom headers to be indexed.
-Add support for automatic tagging of new messages based on particular
-search criteria, (likely using an InMemory database for the new
-messages).
+Add support for configuring "virtual tags" which are a tuple of
+(tag-name, search-specification). The database is responsible for
+ensuring that the virtual tag is always consistent.
+
+Indicate to the user if two files with the same message ID have
+content that is actually different in some interesting way. Perhaps
+notmuch initially sees all changes as interesting, and quickly learns
+from the user which changes are not interesting (such as the very
+common mailing-list footer).
+
+Fix notmuch_query_count_messages to share code with
+notmuch_query_search_messages rather than duplicating code. (And
+consider renaming it as well.)
General
-------
Investigate why the notmuch database is slightly larger than the sup
database for the same corpus of email.
+
+Xapian
+------
+Fix defect #250
+
+ replace_document should make minimal changes to database file
+ http://trac.xapian.org/ticket/250
+
+ It looks like it's going to be easy to fix. Here's the file to
+ change:
+
+ xapian-core/backends/flint/flint_database.cc
+
+ And look for:
+
+ // FIXME - in the case where there is overlap between the new
+ // termlist and the old termlist, it would be better to compare the
+ // two lists, and make the minimum set of modifications required.
+ // This would lead to smaller changesets for replication, and
+ // probably be faster overall
+
+ So I think this might be as easy as just walking over two
+ sorted lists looking for differences.
+
+ Note that this is in the currently default "flint" backend,
+ but the Xapian folks are probably more interested in fixing
+ the in-development "chert" backend. So the patch to get
+ upstreamed there will probably also fix:
+
+ xapian-core/backends/chert/chert_database.cc
+
+ (I'm hoping the fix will be the same---an identical comment
+ exists there.)
+
+ Also, if you want to experiment with the chert backend,
+ compile current Xapian source and run notmuch with
+ XAPIAN_PREFER_CHERT=1. I haven't tried that yet, but there are
+ claims that a chert database can be 40% smaller than an
+ equivalent flint database.
+
+Report this bug:
+
+ "tag:foo and tag:bar and -tag:deleted" goes insane
+
+ This seems to be triggered by a Boolean operator next to a
+ token starting with a non-word character---suddenly all the
+ Boolean operators get treated as literal tokens)
