Hi pfote ! 🙂 Sorry for the late reply.
I'm excited to see someone using My Little Word Land to use Japanese! ^_^
One of my goals when building My Little Word Land was to have the learning directions be customizable, which is very handy with Chinese (the language that I'm learning) and I think should also be handy for Japanese 🙂
You should be able to freely choose the learning method by clicking the three dots ("…") that are to the right of the learning methods and clicking "Show less common testing methods". A lot of people have asked how to do this, though, so I probably should find a way to always show those testing methods. Some courses may also need to have one of their columns marked as a pronunciation column. I tried to do this via a script, but I'm guessing it missed a lot of courses 🙂
I really like your suggestion to be able to review in any direction after learning a word! :D
I think that'd probably make more sense than the current method of needing to learn a word in each direction before reviewing it in each direction.
