Hello, I would like to be notified[1], when a todo item enters the warning period, scheduled time, or deadline.
I can imagine writing a function, that executes every 5 minutes, that scans all agenda files calling `org-get-[scheduled,deadline]-time', but I hope, that there is already something, that I can use more easily. TIA for any help, Peter Footnotes: [1] For notifying, I'll use an external program, for example "notify-send", because the emacs window is not always visible.
