| In the current Mantis system, all shared categories must either be created or copied between projects and subprojects by hand. Modifying one category means manually modifying every other project that category exists in to reflect the same change. There is also no way to handle global categories other than to copy categories from one project to every other project. Adding a new project or subproject later means more work to copy categories to it as well. | In the current Mantis system, all shared categories must either be created or copied between projects and subprojects by hand.
