Most conferences, barcamps and similar events offer their plan of sessions and talks in the iCal format for importing into your calendar. However importing a whole session plan into your standard calendar renders it pretty much useless for anything else.
Giraffe allows you to import the schedule into a separate list giving you a simple overview on what happens on the conference. Besides the session title and datetime it also lists the speaker, location and description if available in the iCal url.
Sessions can be bookmarked and the list can be filtered by favorites and upcoming talks.
