This is pretty simple.
Usually, when I want to open a new note, I almost always want to keep my previous note open. Ctrl + N opens a new note, but takes me away from the note I am in. I would like to by able to hit either Ctrl + N or Ctrl + Shift + N and open a new note in a new pane.
If you would like this too, or would like a variation of this, please let me know!
