What are the most useful kinds of extensions?

I've heard of five:

	singular - if one move is clearly better than all other moves

	promotion threat - if a pawn moves to the 7th rank

	recapture - a recapture restoring previous material difference

	check - if a move is a check

What other extensions are there that have proven useful?
