Excerpts from my org-mode configuration:

As you can tell, I'm a huge user of agenda and org-capture, and also keep my org files synced via Dropbox.

I don't document my configs much, so friendly reminder for readers of mine (and others) - you can find documentation for any variable from within Emacs, by pressing C-h v (or M-x describe-variable), and for any function by pressing C-h f (or M-x describe-function).

try-load-and-configure-library is a small macro I wrote long before I found out about use-package.

  (defmacro try-load-and-configure-library (lib &rest configuration)
    (declare (indent defun))
    `(when (locate-library (symbol-name ,lib))
       (require ,lib)
       ,@configuration))
