Great for this beginner

I’m new to the game and using this app as a learning tool. I have two problems with it. Sometimes it is hard to distinguish between the queen and the bishop with the black pieces (which are really brown against a brown background) and I wish it was possible to replay a particular move after I’ve made it when I discover it was a poor move. I realize this doesn’t happen in “real” chess but remember I’m using this as a leaning tool
Otherwise I love it.
