I would really like to be able to have an .ical feed only bring in current or future events as I have all the events in my calendar (from as long ago as 10 years) clogging it up with useless data. I do not have control over the calendars that feed into mine and if I delete the older items, they are re-imported on the next go-round.
This may speed up the overall plugin because it would not have such a large database.
