++ add notmuch-message-mode
+
+ This should allow us to override many of the default behaviors of emacs message mode without affecting people using message mode from gnus
+ Things we'd might want to allow here include
+
+++ select from address (with the configured email addresses as default choices to pick from)
+++ set user-agent string
+
++ allow different "real names" for the optional email addresses
+
+ if only one name is configured, use that for all addresses;
+ if other_names are configured, match those with the other_email addresses
+
## notmuch
+ Add folder keyword
allows for searches based on the arrival path
++ Add Reply-To: header to the indexed header components
+
+ allows for searches based on the return address
