About Columnary
A horizontally scrolling column reader for Chrome.
It bothered me that despite all the space on my laptop screen or desktop monitor, reading web articles felt like breathing through a straw. Horizontal space is poorly used and vertical space is in short supply, leaving only a few paragraphs on screen at once.
Columnary is a Chrome extension that makes full use of your screen real estate, whether it's a small screen laptop or a 5K monitor. It strips ads and formatting, and puts everything into columns in a horizontally scrolling format. This way, articles can fill 100% of your screen while keeping line lengths readable.
This transforms the way your brain processes articles. When you can see the whole thing at once, you can utilise your natural spatial processing ability to make sense of where you are.
After installing it, you can go to chrome://extensions/shortcuts to assign a keyboard shortcut to open Columnary.
Once you open the Columnary reader view on a webpage, keyboard controls available are:
Left/Right: scroll
Shift-Left/Shift-Right: scroll by column
F: fullscreen
Esc: exit fullscreen or exit Columnary
Features:
* Bookmark feature to mark your place and return to it on long articles
* Settings panel with typography control
* Colour scheme is light mode or dark mode according to your system settings
* Scroll vertically to scroll horizontally
