+\r
+Summarizing, I see 3 related changes here\r
+\r
+- fixing the code to let-bind message-hidden-headers instead of globally\r
+  modify it\r
+\r
+- adding in-reply-to notmuch-mua\r
+\r
+- providing a keybinding to toggle visibility of hidden headers that\r
+  works better than the current use of widen\r
