Kindly Mode provides Amazon Kindle-like view mode to Emacs.
Before using Kindly Mode, you must eval or add the following code into your .emacs:
(require 'kindly-mode)
As Kindly Mode doesn't have specific relations to any file extensions, it won't be enabled until you enable it explicitly -- by M-x kindly-mode :).
I don't know how to install Emacs extensions other than Auto Install.
(auto-install-from-url "https://raw.github.com/fukamachi/kindly-mode/master/kindly-mode.el")
- Better appearance to read.
- vi-like key bindings.
- Puts a bookmark automatically when Emacs is idling.
