A scrum-like todos plugin for Redmine. Allows easy creation and management of infinitely nestable todo lists on a per project basis, that in the future will be able to be organised into sprints(or releases). Also provides global 'My Todos' for all projects. Todos can be allocated to uses, and tied to Redmine Issues.
Allowing commenting on todos would make it very close to BaseCamp functionality (it's the one main thing missing).
