I want to set a custom "look ahead" period for the Events pane, as 5 days is too short to remind me sufficiently of birthdays and so on, for which I have events saved.
I've tried Googling around for (what I think are) the relevant keywords, and also searched the Forum, but it sadly didn't help. I also asked in the #palemoon IRC channel but was recommended to post here instead.
