I came here to request this too. Mixing tasks and calendar events together on the same day would be much easier for me. Otherwise, there are two timelines to monitor instead of one.
E.g.
Current
Task on Day 1
Tasks on Day 2
Tasks on Day 3
Calendar Events
Suggested
Tasks & calendar events on Day 1
Tasks & calendar events on Day 2
Tasks & calendar events on Day 3
Edit: It seems what I wanted is already discussed over here.
