I think I follow what you would like.
The mini control in the right panel actually follows what your selection is. If you select a note with a date tomorrow, that calendar will show you tomorrow, so you can see what is relevant to what you are editing.
If there is no selection, it shows today. I guess what you are requesting is that by default, when there is no selected note, you could have some setting for what is showing. Instead of just today, you could perhaps choose to always have the coming week shown there. Is that what you mean?
