HyperList.vim is a Vim plugin for handling HyperLists. HyperList is a methodology to describe anything: any state, item(s), pattern, action, process, transition, program, instruction set, etc. HyperList can be used as an outliner, a TODO-list solution, a project management tool, a business process management aid, a data modeler, a use case facilitator, or for any other application that makes use of descriptions of states or transitions. This plugin does both highlighting and various automatic handling of HyperList, like collapsing lists or parts of lists in a sophisticated way. Since HyperList.vim can also encrypt your lists, it can be used as a very structured password safe.
