Firstly I want to say the Review innovation is one I really appreciate.

To further improve it I want to suggest the following:
* Have more Review periods;
- 1 month
- 3 months
- 6 months
- 1 year
* Allow a comparison of periods for specific repeated tasks
* Introduce a Skip or similar function for uncompleted tasks that can be seen in Review for tasks not completed on day X but allows a person to remove from their ToDo list
