Been playing around with it and it is very flexible and adaptable. The UI is lovely to look at as well. There are not many simple task managers that offer a horizontal scrolling calendar so I am thrilled to find this one!
No weekly planner on the market is doing a good job in my eyes. Weekplan is too crowded interface. The best in my eyes is teuxdeux as the UI is very good (everything on one screen, weekly view on top/list and backlog in the bottom) but they don't improve this tool any further.
Tidily combines the visibility of a kanban board with the structure of a calendar, together with the simplicity of a to do list. Easy to set up yet with just the right level of functionality to make it useful.
