To solve the wide-screen, narrow text problem, I once threw together a demo with a hacked up Chromium/WebKit to create a flowing, multi column view mode that created a long virtual scroll surface and scrolled it like newspaper columns: https://vimeo.com/59463521.

It wasn't super intuitive, but wish a modern browser had this.

I'm kinda sure I saw a pre-chromium Opera browser build do this back in like 2010 or so (maybe it was just a mockup), but like you say, it's not super intuitive. And the scrolling feels weird when you have 2-3 columns moving.

This is a nice feature that I often wish every text editor supported natively.
