Heavy use of shortcuts, has unique concept of blocks with different types (i actually like it a lot). Blocks can have type of code (and can be formatted). In Math blocks lines are evaluated as expressions with results at the end. Can execute golang code.

Kind of controversial take on note taking systems. I can relate though, because i was lost in a burden of creating perfect knowledge management system for a long time without creating any knowledge. Simplest approach with commonplace notebook is what working for me now.

Most heart-stopping writing comes from synthesizing the previously unarticulated in the moment. Rather than reaching for your database, try channeling what’s in the air at this very second. These read/write errors are what we call originality.
Leonardo da Vinci kept all of his notes in one big book. If he liked something he put it down. This is known as a commonplace book, and it is about how detailed your note-taking system should be unless you plan on thinking more elaborately than Leonardo da Vinci.
Shun the useless adoption of the aesthetic of the useful. When something can be like work or like play, never make it work.
