In one place, in familiar looking space, user can keep the various To-Do lists used in office work as well as shopping lists. User also can assign subtasks to any task. User can define which part of any task is already done to see the overall progress. It is also possible to move tasks freely within the list so he / she can set up his / her own priorities and change them at any time. With List Manager user can finally have some kind of simple but still effective project management tool at hand wherever he / she is!
