Not a popular opinion I'm sure, but I'm all-in on OneNote. Works everywhere (at least basically) and it is just so rich. Full pen support for drawing (vital for me), tables, equations (sort of), multiple text blocks on a page (also key!), internal & external links, fast search (as of last year). Search is good enough that I rarely use tags anymore.

Yes, it's totally vendor locked in and I do hate that. And no syntax highlighting for code is annoying. Lack of markdown is a pain. And it's bug-ridden and closed source.

But I've been using it for my work daily journal and knowledge capture for a few years now, and it's so fluid and easy to jot down or scribble a quick note and find it later that it's hard for me to imagine going back to a basic Markdown editor. It's the closest thing I've found to a searchable paper lab notebook.

And btw I'm a hardcore Emacs user for the last 40 years. Org mode is great, but for me, OneNote kills it in expressiveness and fluidity of idea capture and recall.

If someone makes a Markdown editor that supports pen/tablet ink drawing and multiple text blocks on a page, I'd be interested.
