Hey, this is my first elisp programming so I'm quite certain this is a
big hack.  I just stole elements from elsewhere in the file.  I'm hoping
this is good enough to get accepted then perhaps someone with more taste
would be able to refactor it to be a bit better.

Let me know if I need to change anything.

Subject: [PATCH] org-colview.el: Add support for time units to est+

* lisp/org-colview.el: Add support for time units in est+.  Ranges are interpreted just like non-range estimates.

Yes, indeed: the first thing you should do is explain what you are
trying to do.  E.g. what does "est+" mean? Once you have explained
*what* you are trying to do, then somebody might be able to suggest
*how* to do it better (if it is a worthwhile thing to do in the first place).

I'm not sure I understand your question.  est+ is an existing functionality
in columnview that is documented. I've brought it closer to the regular
effort functionality by supporting time units.

That's not bad. Thank you.

You need to provide the name of the function being modified:

Could you expound the docstring? In particular, it should make the
output format predictable. See `org-columns--summary-apply-times' for
example.

There is much code duplication with `org-columns--summary-apply-times'.
It would be better to avoid it.

We may want to create a new function turning a list of durations into
numbers (with `org-columns--time-to-seconds) and adding the type of the
expected output, as a symbol, in front of the list. Then both
`org-columns--summary-estimate' and `org-columns--summary-apply-times'
could use it.

It would mean we would process the list of estimates two times, but
I don't think it matters much in practice.

If you have an implementation for that, feel free to include it. Do not
consider it a blocker, tho. We can always factor this out later.

> +      (format "%s-%s" low high))))

You don't need to `truncate' the estimates.

I don't think the default output format should be "%h:%.2m". If no
special format is present, I think the traditional "%.0f" can be used.

Also, the duplicate `cond' can be factored out. The whole part above can
be written (including suggestions aforementioned):

    (mapconcat (lambda (time)
                 (cond
                  (duration-flag (org-minutes-to-clocksum-string (/ time 60)))
                  (hms-flag (format-seconds "%h:%.2m:%.2s" time))
                  (t (format "%.0f" time))))
               (let ((sd (sqrt var))) (list (- mean sd) (+ mean sd)))
               "-")

It would be nice to add a bunch of tests for various estimates formats.
`test-org-colview/columns-summary' in "test-org-colview.el" contains
already many examples to boot.

Eventually, could you add an entry about this new feature in ORG-NEWS?
