Agenda view will definitely be the most popular view if implemented correctly, I suggest you take some inspiration from the agenda view in Routine.

I would love to see the "start and end time" of my tasks entered in the calendar in the calendar as you can see them in the agenda view in the mobile app.

I plan my day by first creating tasks and entering the time I need for them, then dragging and dropping them into the calendar. It would be much easier if I could see the exact start and end time of each task in the calendar underneath the name of the task just like in the agenda view in the mobile app.

Stefania Calendar agenda view on my phone never opens to the correct day! It often opens months away from the correct date.

This is a must have, in Google Calendar I am 100% always on the agenda view.

Also can we have the possibility to choose the start and end time for the calendars views? For example if I choose 7am to 9pm, that is all the time that will show in the calendar.

All that white space for 12 midnight to 66am is quite irritating for me

This looks amazing. I love the screenshot in the comments!

This would likely be my most used view. Once I plan my day, I live in the Day view. I love that side panel showing the chosen event/task in detail for any notes, subtasks etc. instead of the pop-up view that we use today. My only question on this view: where do today's tasks without a time defined go since they're not scheduled to a specific time; just today? Maybe at the top of the agenda schedule, like an all-day section?
