First of all, love love love Renshuu. Been using it for years and will probably use it forever. I recently got a perfect score on the N2 and I just have to credit Renshuu.
Anyway, my request is this:
I like the Quick Draw game, but it would be really nice if you could pick the kanji you want to study. Right now it's a bunch of pre-made lists mixed with kanji I know and don't so I never really end up using it.
Or you know how you get a custom crossword on your vocab schedules? It would be so cool if the kanji schedules had an attached Quick Draw game!
However you choose to implement it, just any way to play Quick Draw with anything other than the pre-made lists would be amazing.
