Hello, I reported a possible bug a couple of weeks ago and since then I have notice related bugs in todays HEAD (that may have existed before).
1) The column view of TODO items only shows the total Effort at the top and the Effort for the last item, 2) The column view of the org-agenda (restricted to current buffer with '<', get list of todos with 't') only shows the Effort for the last item and the total Effort at the top shows the same value as for the last item 3) Narrowing by tag (the original possible bug reported) shows similar behaviour as above Myles
