New idea for the trophy
I started practicing spanish before going on holiday to Spain. I figured out that I do nor really need advanced grammar, but have to have quick responses to be able to have real conversations. Therefore I went back to the very basic lessons which I did long time ago and I now only do the quick practice repeatedly until I beat the clock. Then i move to the next one.
It would be great help and also big motivation if skills tree would show somehow in which lessons I have already beat the clock. I think this is also much more accurate indication that one have learned particular lesson.
