Lack of functionalities for the new To Do app

Hi,

Why the new To Do app does not have some key functionalities that the old version had, like

1) being able to create new Views

2) being able to select multiple tasks and move them in one go to another date

3) see flagged e-mails and tasks in one list

4) add columns

...

Difficult to understand that Microsoft develops a new app that is worse that the old one.
