It's interesting WTF did you do it? Thank you.
Yeap! Kind of a "Links sub search" in each note - if you find another note from that search and press enter it adds a reference to current note on that note you just clicked. Example: If i want to connect my vectors note to linear algebra, machine learning and so on: I just need to find this 2 notes on my Vectors note "Links sub search" and press enter twice...
