I'm puzzled why this is headlined as an alternative to Typora.

I'm a happy, paying Typora (on macOS) customer. Looking at the linked page, I would never have guessed that IF is at all a Typora competitor.

I love Typora because it is a great, flexible WYSIWYG-ish Markdown editor (at least for me), and that is how it bills itself: “A minimal Markdown editor and reader.”

The linked page about IF doesn't mention Markdown at all… but it does mention things like “todo” and “pomo” and “schedule”. What do those have to do with editing Markdown?
