-  Maildir, usually called FCC (file carbon copy). You can achieve this
-  by setting the variables `message-directory` (which defines a base
-  directory) and `notmuch-fcc-dirs` which defines the subdirectory

+## How to customize `notmuch-saved-searches`
 
-* <span id="customize_notmuch_folder">**How to customize notmuch-folders**</span>
+When starting notmuch, a list of saved searches and message counts is
+displayed, replacing the older `notmuch-folders` command. The set of
+saved searches displayed can be modified directly from the notmuch
+interface (using the `[save]` button next to a previous search) or by
+customising the variable `notmuch-saved-searches`.
 
-  There's a "notmuch-folder" command available in the emacs client
-  that displays a list of "folders" and the number of messages in
-  each. Each folder is simply a named search specification. To
-  configure this mode, edit your ${HOME}/.emacs file and include text
-  something like the following:
+An example setting might be:
 
-		(setq notmuch-folders '(("inbox" . "tag:inbox")
-					("unread" . "tag:inbox AND tag:unread")
-					("notmuch" . "tag:inbox AND to:notmuchmail.org")))
+		(setq notmuch-saved-searches '(("inbox" . "tag:inbox")
+				("unread" . "tag:inbox AND tag:unread")
+				("notmuch" . "tag:inbox AND to:notmuchmail.org")))
 
-  Of course, you can have any number of folders, each configured
-  with any supported search terms (see "notmuch help search-terms").
+Of course, you can have any number of saved searches, each configured

-  Personally, I find it fairly useful to add "not tag:delete" to those
-  views as I use that tag to mark messages as deleted and it
-  automatically removes them from my standard views. Use whatever
-  seems most useful to you.
+Some users find it useful to add `and not tag:delete` to those
+searches, as they use the `delete` tag to mark messages as
+deleted. This causes messages that are marked as deleted to be removed
+from the commonly used views of messages.  Use whatever seems most
+useful to you.
 
-* **Viewing HTML messages with an external viewer**
+## Viewing HTML messages with an external viewer
 
-  The emacs client can often display an HTML message inline, but it
-  sometimes fails for one reason or another, (or is perhaps inadequate
-  if you really need to see the graphical presentation of the HTML
-  message).
+The emacs client can display an HTML message inline using either the
+`html2text` library or some text browser, like w3m or lynx. This is
+controlled by the `mm-text-html-renderer` variable.
 
-  In this case, it can be useful to display the message in an external
-  viewer, such as a web browser. Here's a little script that Keith
-  Packard wrote, which he calls view-html:
+The first option is theorically better, because it can generate
+strings formatted for emacs and do whatever you want, e.g., substitute
+text inside &lt;b&gt; tags for bold text in the buffer. The library, however
+is still in a very early development phase and cannot yet process
+properly many elements, like tables and <style> directives, and even
+the generated text is often poorly formatted.
+
+Among the available browsers, w3m seems to do a better job converting
+the html, and if you have the w3m emacs package, you can use it,
+instead of the w3m-standalone, and thus preserve the text formatting.
+
+But if the rendering fails for one reason or another, or if you really
+need to see the graphical presentation of the HTML message, it can be
+useful to display the message in an external viewer, such as a web
+browser. Here's a little script that Keith Packard wrote, which he
+calls `view-html`:
 
 		#!/bin/sh
-		dir=3D`mktemp -d`
+		dir=`mktemp -d`
 		trap "rm -r $dir" 0
 		cat "$@" > "$dir"/msg

+for email coming from your company email address, and your personal

+on the command line (the -f/--from option) it will automatically
+pick the matching account.  The only trick here seems to be getting
+emacs to actually pass the envelope from.  There are a number of
+overlapping configuration variables that control this, and it's a
+little confusion, but setting these three works for me:

+If you have a hard time getting the above to work for you, as I did,
