Apart from Logseq’s whiteboard feature, do consider checking out logseq’s actual workflow (adding stuff in journal etc.). It does have a learning curve, but you might end up liking it more than Onenote’s.

I third logseq 😅

Has a (small) learning curve. But powerful once you learn it.

It takes a while to open the first time though.
