statistical

Hello, I hope you are well?
I would have liked to have the following functionality

1- able to modify the parameters of a task (for tasks to be done over a period of one week, be able to modify from 2 times per week to 3 times per week)

2- be able to put a description for the tasks (not just the name of the task)

3- a lot more statistics, and global statistics, not just on a single task
