If I understand your request correctly, we had the samme issue last october, and then this proposal was suggested to pin the daily note to a side pane. In your case, you’d first open a new note, and drag it to the location you want in the lower right, pin the note, and then enter the stuff as suggested in the other thread.
I don’t think there’s a way for your dashboard to reuse a tab to reload a given file, but I’m not sure which plugin you’re screenshot is from, so I might be mistaken.
