Provides a SideKick-like tree which displays folds rather than language-specific structures. Outline will work with any folding mode other than the SideKick folding mode. That would be a waste of time as it would just be duplicating the SideKick Structure Tree.
See the Wiki page for old info by the original author.
Bugs and feature requests can be submitted at SF.net jEdit Plugin Bugs Tracker. Be sure to put Outline: in the subject.
