I can never convince the app to work on my (very rubbish) phone, but the moons thing is clearly a good idea. I’m always one for better organisation! (and maybe one day I’ll have a phone that doesn’t die upon seeing the memrise app…)
Also, excellent photoshop work @Fenxy – that’s dedication to an idea, right there!
Don’t see why they wouldn’t, really… I mean, it’s logical to break things up to make them feel more accessible, that completing a section is an attainable goal, which will be easier if categories can be divided up a bit if they get too big (but still coming under one main, sensible heading… Like having a language with a Common Materials section, then subheaded by Metals, Fabrics, etc…). On the other hand, memrise might think it’s an unnecessary over-complication that could put people off using the app, I guess. There’s always two sides to everything.
