toggle flash card creation or ask for confirmation before making one
I've just discovered ReadLang a few days ago and love it. Beautiful job.
I do find the automatic flash card creation feature very useful, but sometimes I want to turn it off to just practice reading and keep my word list tidy. I'm new to reading Spanish and tend to highlight a lot (for the translations). Most of what I highlight I don't want saved in my word list. Alternatively, I'd probably be happier if it asked me to confirm each time it wanted to create a flash card.
Anyway, based on your last blog post I guess you're done working on features like this. That's fine, but I thought I'd give my feedback anyway.
