For Speed Memorization

As an accountant I work with numbers all day and this is a great app to refresh my mental arithmetic. However,an additional functionality in the preferences that would allow a user set an arbitrary time limit per problem would be awesome. For example, a set of 30 problems with only 2 seconds to solve before the program moves on to the next problem. When you get better you could set it down to 1 second. That would allow the user to know which problem sets he or she truly has memorized, and allow the user to focus on the weaker areas. Just spitballin.
