Wish I hadnt bought the full version

I wanted to open up all categories, so I bought the full app. The unfortunate thing about the full version is that, in the "guess the item" section, you cant choose which category to review. The only option is to review all categories at once. It was more useful when my daughter could review just animals in this section. I would like to have the option to choose each category separately, then as my daughter advances, finally have the option to do everything at once. If this option were available, it would be among the top educational apps for kids my daughters age (just past 1 year old). As it is, I wish I had just stuck with the older locked/free version
