Calendar app concept

I had the idea because i have tried a bunch of calendar, to-do's and reminders apps and i haven't found one i loved, so i came up with this concept of how the perfect one for me could look like.

It's supposed to work by zooming in and out from task to day to week to month, it uses color and emojis for association between tasks and categories or urgency, whatever the user chooses, each task can be created as complex or as simple as the user wan't with only a couple of fields appearing at first but with the ability to add as many fields and properties as necessary, such as time, date, category, color, description, reminder, check list, people, location, etc.
