+Hello\r
+\r
+I agree that the unread tag does not work well. There are some instances\r
+which I would class as plain bugs (notmuch-show-next-message which is\r
+bound to N marks the new message read even if it is collapsed) and\r
+other instances where it is not clear what the correct behaviour should\r
+be.\r
+\r
+I have messed around a bit and there seem to be a lot of possible\r
+variants and I don't know whether any would have any consensus.\r
+\r
+One clear divide is whether we should only mark "visited messages" (ie\r
+ones reached using space, n,N,p,P etc in the current bindings) or we\r
+should also make messages seen by scrolling past (eg with page down).\r
+\r
+Anyway here is a list of some possibilities. In all cases I assume we do\r
+not mark any collapsed message read.\r
+\r
+1) Mark a message read when we visit it.\r
+2) Mark a message read when we visit it and the leave it with a "visit\r
+move" (eg n for next message)\r
+\r
+3) Mark a message read if we see the start of the message in the buffer.=20\r
+4) Mark a message read if we have seen the start and end of the message\r
+in the buffer.\r
+5) Mark a message read if we see the end of the message after seeing the\r
+start (rationale moving to the top of the buffer is likely "movement"\r
+rather than "reading")\r
+\r
+6) Something based on how we leave the message: eg page down could mark\r
+all messages which were fully visible read, n (next-open message) could\r
+mark the message being left read.=20\r
+7) Similar to 6) but something where read necessarily includes have seen\r
+the start of the message.\r
+\r
+I think all of these are reasonably easy to implement, and I think I\r
+know which I would like (something like 5 or 7) but it would be\r
+interesting to know if there is any general view or any view on how\r
+customisable this should be.\r
+\r
+Does anyone have any thoughts?\r
+\r
+Best wishes\r
+\r
+Mark\r
