We are expanding support of lightweight formatting to include additional Markdown syntax features. This includes strikethrough formatting and nested lists. To get started, explore these new options in the formatting toolbar, keyboard shortcuts, or by editing the Markdown syntax directly.

A headline and some bulletpoints, wow.
Wake me up if it supports pretty code syntax highlighting (like Dillinger), internal linking (like Silverbullet or Obsidian), tagging, table of contents for headlines and a proper advanced search for content.
It doesn't even need to have the advanced stuff like graphs, content embedding, scripting and theming.
frankly I think that even the markdown support is too much for notepad. it's supposed to be a raw text editor, why does it need new features? It was a finished product already
