+Hi\r
+\r
+I have read this patch and am broadly happy with it. In particular I do\r
+not think I have any "design concerns" with this version: I think\r
+picking the tags from the visible messages is fine and this version\r
+avoids the query and the thread-id stuff.\r
+\r
+On the loading library issues I defer to Adam and Tomi.\r
+\r
+I do have a couple of comments on the current version\r
+though. First the patch is very big. I would prefer it split into\r
+several pieces something like:\r
+\r
+1) Add tags to the headerline but not clickable \r
+2) Add the header-button library if appropriate\r
+3) Add notmuch-tagger and change headerline to buttonize the tags\r
+4) Add the tests.\r
+\r
+The first would be small and uncontroversial I think, for the second it\r
+would not really be code review just "do we want to do it this way" as\r
+is being discussed in the other thread. The third obviously has the meat\r
+of the series and 4 is relatively innocuous.\r
+\r
+Possibly you could also split the add clickable buttons to tags in the\r
+buffer and add clickable buttons to headerline tags as two separate\r
+steps.\r
+\r
+One advantage of the split is that it would be easy to see who had\r
+reviewed which bits. For example I have not read the\r
+header-button-library bit or the tests but have looked at the rest.\r
+\r
+\r
+My other comment is on your comments in notmuch-tagger\r
+\r
+> +(defun notmuch-tagger-present-tags (tags &optional headerline)\r
+> + "Return a property list which nicely presents all TAGS.\r
+> +\r
+> +If HEADERLINE is non-nil the returned list will be ready for\r
+> +inclusion in the buffer's header-line. HEADERLINE must be nil in\r
+> +all other cases."\r
+\r
+I find it odd to say what it returns if HEADERLINE is non-nil and then\r
+say otherwise HEADERLINE must be nil. Could you say what it returns in\r
+the nil case? Something along them lines of\r
+\r
+"if HEADERLINE is non-nil the returned will be ready for inclusion in\r
+the buffer's header-line (i.e., will use header-buttons if\r
+available). Otherwise it returns a list?? ready for inclusion in a\r
+buffer."\r
+\r
+Best wishes\r
+\r
+Mark\r
