The current intention of hitting Cmd-K without typing anything is to quickly navigate to recently viewed notes.
I like that idea.
However my cmd-k list is usually mostly populated with Daily Notes, because it's so easy to be scrolling around between various recent daily notes.
Since there are so many good ways to quickly access daily notes already (scrolling, or using the calendar picker) I would propose to
exclude daily notes from the 'recently viewed' list in the cmd-k modal
.
