The day view of my org-agenda in org-agenda-log-mode shows the estimated effort for each entry (e.g., the
0:45, etc)---I'd like to remove that if possible. Is there any way to edit what columns are shown in the log mode?
That's controlled by the variable
org-agenda-prefix-format which has different settings for the agenda, todo, tag and search display. You can find the value with
C-h v org-agenda-prefix-format RET. E.g. mine is at the default value:
((agenda . " %i %-12:c%?-12t% s") (todo . " %i %-12:c") (tags . " %i %-12:c") (search . " %i %-12:c"))
If you look at yours, the agenda part should have a
%e in it: that's what displays the effort and getting rid of that should do what you want. There may be a width and a punctuation char (e.g the
%-12:c part above says: display the category (%c) in a 12-char wide field, padded with spaces on the right (that's the
-12) and followed by a colon (that's the `:)).
You can customize the variable: when you hit
C-h org-agenda-prefix-format RET, you get the description of the variable (which you should read carefully - it is a somewhat complicated variable) as well as its current value, plus you get a link that allows you to customize the variable: that's the easiest way to modify it. In the customize buffer, just edit the format string associated with the agenda and get rid of the %e spec (including the width stuff in between the
% and the
e, if any).
