Words are now highlighted while listening to an article on artificialfeed.com but it took me a while to figure out how to do it properly.
Could you toy with adding favicons to the websites?
Yes, it's planned. But I want something of higher quality, so I have to manually get the best logo of each website.
Do you only allow a limited amount of sources? Because this wouldn't be cost-effective. Favicons are very small to begin with and, I imagine, can be retrieved server-side.
