 - `lynx` - view HTML email in neomutt.
 - `notmuch` - index and search mail. Install it and run `notmuch setup`, tell it that your mail is in `~/.local/share/mail/` (although `mw` will do this automatically if you haven't set notmuch up before). You can run it in mutt with `ctrl-f`. Run `notmuch new` to process new mail.
 - `abook` - a terminal-based address book. Pressing tab while typing an address to send mail to will suggest contacts that are in your abook.

 ## New stuff and improvements since the original release
 
+- `mw` is now scriptable with command-line options and can run successfully without any interaction, making it possible to deploy in a script.
 - `isync`/`mbsync` has replaced `offlineimap` as the backend. Offlineimap was error-prone, bloated, used obsolete Python 2 modules and required separate steps to install the system.
 - `mw` is now an installed program instead of just a script needed to be kept in your mutt folder.
 - `dialog` is no longer used (le bloat) and the interface is simply text commands.
