I'd like to show an additional property (e.g. EFFORT) on the same line as my tasks, so that it is always visible in both org-mode and agenda view. An example is below.
Current display:
TODO [#A] Description of my task <2019-11-18> :tag1:
:PROPERTIES:
:Effort: 15
:END:
I'd like something like this:
TODO [#A] [15] Description of my task <2019-11-18> :tag1:
Is this possible, preferably not using column view? Thanks.
I don't know how to get it in to both normal view and the agenda view. But, in case it's helpful, one simple way to get effort into headlines in to the agenda view at least, is to edit org-agenda-prefix-format.
(Also with this, you are restricted as to where exactly you can place the effort indicator. The prefix is everything before the headline itself, so you can't put the effort after TODO for example).
That said, here is how I do it:
M-x customize-variable
Customize variable: org-agenda-prefix-format
Look specifically for the agenda value. The default value of this is:
%i %-12:c%?-12t% s
I have changed it to:
%i %-12:c%?-12t [%-4e] % s
It's the [%-4e] that adds in the effort indicator.
So,
GTD: Sched. 7x: TODO [#A] Do the thing
becomes
GTD: [0:15] Sched. 7x: TODO [#A] Do the thing
See describe-variable (C-hv) for org-agenda-prefix-format for more details on formatting options.
(org-agenda-set-effort) - C-c C-x e.
In normal/org mode you could use overlays, although I was told Org does similar things which might get in the way (see here). For now @ngm's answer is probably your best option, but in case it helps, here's one way to solve the first part of your question:
(add-hook 'org-mode-hook
(lambda ()
(org-map-entries
(lambda ()
(let (match-end)
(when (looking-at org-complex-heading-regexp)
(setq match-end (or (match-end 3)
(match-end 2)
(match-end 1)))
(let ((ov (make-overlay match-end (1+ match-end))))
(overlay-put ov
'display
(when-let (ef (org-entry-get nil "Effort"))
(org-add-props
(concat " [" ef "] ") nil
'face 'bold))))))))))
