Abstract: Schemes providing master list functionality that allows a user to reorder to-do items from across multiple projects and/or multiple project management tools. Such schemes can ensure that whatever project management tools the user and others associated with the various projects are using at any time, changes in their task planning will be reflected both in the master list and across all other projects and project management tools, as needed. The necessary hierarchy is maintained by creating an absolute order between different projects and reflecting changes in task order in both directions.
