I'm afraid this feature is too specific, but let's try!
Navigating using VIM keys is incredibly efficient. A more complete implementation as we see in plugins for VS Code or Sublime would be fantastic, however, a "browse" mode as we see in Gmail or Remember The Milk would also streamline the routine a lot.
Ex:
CMD + ALT + V = Toggle Vim Mode
Vim Mode On
J = Next node of the note
K = Previous node of the note
/ = Search on this note
I = Disable Vim Mode
ESC = Disable Vim Mode
Tab = Select the next link
R = Replace selection
GT = Open today note
GW = Open Week view
Vim Mode Off
Normal use
Well.. Just some examples.
