I suck at tones in Skritter (although I partially blame this on the voice actress, I can hear my Taiwanese wife's tones just fine), and as a result some 70% of my review ends up being for tones. But here's the thing- I'm studying Skritter mostly for reading and writing, tones aren't as important to me. Yet, I'm forced to constantly drill tones because it's my weak area.
It's gotten so bad I'm forgetting how to write characters because I spend all my time drilling tones instead of
practicing writing! So frustrating! I know I can turn off tones practice, but I don't want to do that because I do want some practice with them, just not not for them to dominate my practice like they currently are.
So, here's my suggestion- can you set it up so that we can emphasize certain elements of practice without having to completely turn them on or off? Say, a simple slider which says something like "not important-somewhat important-important-very important-extremely important" that we can play with to choose our own learning focus? Just have it affect the frequency of review for those elements, and it should be a fairly easy thing to implement.
