Alternative to pcomplete in org-mode?

Question

I'm new to org-mode and really need to figure out how to get completion working for stuff like :tags and #+ options. Apparently org uses pcomplete as the completion backend. Indeed M-x pcomplete (helm) does offer a buffer with long list of completions for #+ (which disappears if you try to expand the buffer). You then have to click on one of the options, which feels pretty kind of clumsy.

Is there a feature complete and mature alternative to pcomplete? I'm used to completions just popping up as I type, and would ideally like to get the same functionality in Org. Alternately, am I using pcomplete wrong?

Update

Here's the full code:

(defun my-org-mode-hook ()
  (add-hook 'completion-at-point-functions 'pcomplete-completions-at-point nil t))
(add-hook 'org-mode-hook #'my-org-mode-hook)

It works!

Answer 1

It depends on how you've configured Emacs so that "completions just pop up", but possibly

(add-hook 'completion-at-point-functions 'pcomplete-completions-at-point)

will do it. If you use company for completions (as I do) and you have company-capf in company-backends (it should be there by default I believe) company should pick up pcomplete completions via completion-at-point.
