The problem with efficiency is that your reviews will pile up & up & up if you add too many cards too fast. In fact I've started taking short breaks in which I intentionally don't enter any new cards so that I can clear out the backlog. Even if you spend 1 whole minute on each card, that is only 20 minutes per day if you're following the recommendations & only doing 20 new cards per day.
I'd like to be able to click unfamiliar words in Chrome and automatically create notes in Anki 2 using an online dictionary. It'd also be nice to have an automatic method for sending text and images to Anki notes straight from Chrome. For example, if I read an article here that I want to remember, I'd be able to highlight the title, send it to Anki, and when I review, I'd see the title on the card's front with the reverse being a link to the source if I forgot what the post was about.
I found some Chrome extensions that purport to do this sort of thing, but didn't get any of them to work with Anki 2. Is anyone currently doing this, and if so, what is the solution?
