Add tasks, dated backlinks and "notes created this day" to the 3-day view as well

Currently, only the day view contains the details of tasks for the day, notes referencing that date and notes having been created on that day.

All other views exclusively show daily notes. If you are not utilising daily notes, these views are completely useless. Here are suggestions for the others:

3-day view

Given the side-by-side layout, on any non-mobile screen I have been using, the room is absolutely sufficient to display exactly the same information provided in the day view. I'd be ok with horizontal scrollbars in case I make the window too narrow.

Week view

Regarding the week view, as stuff is placed underneath each other, limiting the amount of information and have it vertically dense seems reasonable. I'd be happy to see tasks for that date as well as objects of document types that have an explicit date property with the date value pointing towards that date.

Month view

Well, there is not much to be done about this. There certainly are people out there actually using daily notes who benefit from this, but any additional information would certainly be too much.
