About a week ago I developed a browser plugin for chrome and firefox which replaces the new tab page with anki flashcards to review. The idea is that with it, each time I open a new tab I will review a few cards, thus making it more lightweight than an hour-long anki session.
If anyone is interested the code (licensed under The Unlicense) and links to the web stores can be found at https://github.com/corollari/ankiTab
Note: In order for it to work you need to be logged in ankiweb.net
