Whittlepedia is a browser extension that filters Wikipedia pages down to just links, allowing for rapid concept hopping.
A new "See only links" button will be fixed at the top of each page. When clicked, the page will fade out all text except for links, and the button will say "See all text". Clicking again will fade text back in, and the button will go back to saying "See only links".
To maintain the state of the button (and whether or not to affect a page), the extension stores an object with a single boolean flag using the Web Extension Storage API.
The button's text is based on which language Wikipedia is being used in. The text has been translated from English using Google Translate for the top languages on Wikipedia's main page. I would love help making the translations more accurate/idiomatic!
