+Hi,\r
+\r
+The amazing thing about the notmuch emacs interface is that with just a\r
+couple of keystrokes you can quickly manipulate a lot of emails and thus\r
+be very efficient. The big disadvantage is that with just a couple of\r
+keystrokes you can manipulate a lot of emails and thus quickly\r
+completely mess up your emails. Just think about the scenario of a cat\r
+wandering across your keyboard.\r
+\r
+Is there a possibility to log all tagging actions done in notmuch?\r
+Something like:\r
+\r
+<timestamp>, <msgid>, <old set of tags> <new set of tags>\r
+\r
+It would be helpful for restoring things in case something went wrong,\r
+and it could be the start of an undo function.\r
+\r
+ Sebastian\r
