I'm new to renshuu, and so far I find it great. I did try study schedule, it's really nice, but somedays are busy and I don't feel like adding more content to my review pool, and would prefer to only do reviews to flush what I need to work on. Is it possible to do that ? I havent found how, because when I click study, it always force me to learn new items, then quizz with those new items.
First, instead of clicking the Study button, click the little Settings icon just next to it. From there, you should see a Yes/No switch for adding new terms. Just turn that off!
