This release introduces folding. Once the details are fully worked out, folding will graduate from experimental status and will be made available in other modes, too. Folding lets you temporarily hide areas of the buffer to create an outline view. If such an operation takes you to a folded area, the fold is expanded automatically. J tries to be smart about folding.
