WYSIWYG
TIL an acronym: WYSIWYG
It stands for What You See Is What You Get, as in manipulating the visual results directly. Underlying representations are abstracted from the user.
I love Notion as a user. In order to explain what it does as a philosophy unlike Markdown or LaTeX (they are WYSIWYM - What You See Is What You Mean btw), I would have to use lots of words to explain.
But turns out, all I needed was an acronym :D
