OneNote lets you add content in a canvas. It would be cool if there was an ASCII canvas note taking tool but I think it would have to be built on plain text from the ground up.
Yeah I meant just within the individual text blocks, the canvas itself can't be Markdown of course
It's such a more convenient way of "styling while you type" and has become the de facto way to do that... in Slack, Reddit comments, GitHub, Jira, Confluence etc... even MS Teams, they all allow Markdown "styling while you type"
