Hi Bastien, In bzr emacs there is a new variable called appt-warning-time-regexp. It contains a string for how many minutes we want to be reminded of an appointment.
For example, to be warned 30 minutes in advance of an appointment you would put the following in the diary file: 2011/06/01 12:00 Do something ## warntime 30 I would very much like this feature in org. How about we use the same regexp? We could use this when we call org-agenda-to-appt. A typical entry would look like this: * Do something <2012-02-04 Sat> warntime 30 What do you think of the specifications? If it's OK with you I will find the time to do it.
