Reading Info v1.1
Shows reading info for text on webpages, articles, and selected text. If the page has an article element it's info will be prioritized. Displays both the total character count with and without white space.
Also shows the number of screen lengths and a progress percentage of how far scrolled down the page is.
Note that the information excludes textboxes and hidden text such as drop downs or tabbed interfaces. Or may include text that might be irrelevant for reading such as long lists of sources, tables, headers, and footers.
Features the ability to change the words per minute reading speed, and an option to show both webpage info and article info. Set a command keyboard shortcut to open the pop-up.
