You can change the overall appearance of the notmuch-hello screen by
-customizing the variable :index:`notmuch-hello-sections`.

+ |docstring::notmuch-show-logo|
+
+.. el:defcustom:: notmuch-column-control
+
+ Controls the number of columns for saved searches/tags in notmuch view.
+
+ This variable has three potential types of values:
+
+ .. describe:: t
+
+ Automatically calculate the number of columns possible based
+ on the tags to be shown and the window width.
+
+ .. describe:: integer <n>
+
+ A lower bound on the number of characters that will
+ be used to display each column.
+
+ .. describe:: float <f>
+
+ A fraction of the window width that is the lower bound on the
+ number of characters that should be used for each column.
+
+ So:
+ - if you would like two columns of tags, set this to 0.5.
+ - if you would like a single column of tags, set this to 1.0.
+
+ - if you would like tags to be 30 characters wide, set this to 30.
+
+ - if you don't want to worry about all of this nonsense, leave
+ this set to `t`.

.. _saved-searches:
``tag:inbox`` to access the inbox and ``tag:unread`` to access all
unread mail, but there are several options for customization:
-:index:`notmuch-saved-searches`

The list of saved searches, including names, queries, and
additional per-query options.
-:index:`notmuch-saved-search-sort-function`

This variable controls how saved searches should be sorted. A value
of ``nil`` displays the saved searches in the order they are stored
in ‘notmuch-saved-searches’.
-:index:`notmuch-column-control`
- Controls the number of columns for displaying saved-searches/tags
-
Search Box
----------
The search box lets the user enter a Notmuch query. See section
“Description” in Notmuch Query Syntax, for more info on Notmuch query
syntax. A history of recent searches is also displayed by default. The
-latter is controlled by the variable :index:`notmuch-hello-recent-searches-max`.

following variables.

Control how to construct a search (“virtual folder”) from a given
tag.

+
+ If the car of an element in notmuch-search-result-format is a
+ function, insert the result of calling the function into the buffer.
+
+ This allows a user to generate custom fields in the output of a
+ search result. For example, with the following settings, the first
+ few characters on each line of the search result are used to show
+ information about some significant tags associated with the thread.
+
+ .. code:: lisp

+
+.. _show-large:
+
+Dealing with large messages and threads
+---------------------------------------
+
+If you are finding :ref:`notmuch-show` is annoyingly slow displaying
+large messages, you can customize
+:el:defcustom:`notmuch-show-max-text-part-size`. If you want to speed up the
+display of large threads (with or without large messages), there are
+several options. First, you can display the same query in one of the
+other modes. :ref:`notmuch-unthreaded` is the most robust for
+extremely large queries, but :ref:`notmuch-tree` is also be faster
+than :ref:`notmuch-show` in general, since it only renders a single
+message a time. If you prefer to stay with the rendered thread
+("conversation") view of :ref:`notmuch-show`, you can customize the
+variables :el:defcustom:`notmuch-show-depth-limit`,
+:el:defcustom:`notmuch-show-height-limit` and
+:el:defcustom:`notmuch-show-max-text-part-size` to limit the amount of
+rendering done initially. Note that these limits are implicitly
+*OR*-ed together, and combinations might have surprising effects.

Sending Mail
------------
-:index:`mail-user-agent`
+.. el:defcustom:: mail-user-agent
Emacs consults the variable :code:`mail-user-agent` to choose a mail
sending package for commands like :code:`report-emacs-bug` and
:code:`compose-mail`. To use ``notmuch`` for this, customize this
variable to the symbol :code:`notmuch-user-agent`.
+.. el:defcustom:: message-dont-reply-to-names
+
+ When composing mail replies, Emacs's message mode uses the
+ variable :code:`message-dont-reply-to-names` to exclude
+ recipients matching a given collection of regular expressions
+ or satisfying an arbitrary predicate. Notmuch's MUA inherits
+ this standard mechanism and will honour your customization of
+ this variable.
