This is a great program for tactics training. First of all, aesthetically, the program is very nice. The program adjusts its difficulty level to how you perform on the tactical puzzles, which is helpful to keep things challenging. The problems do not appear in any "theme order" which is excellent since this simulates more of an over-the-board experience.
I have some suggestions to make a good program into a great program. The following features (reminiscent of the ancient CT-ART program) would greatly improve this software:
1) The ability to resolve all problems which you got wrong would be helpful for training purposes.
2) The ability to resolve all problems already completed would be helpful for drilling
certain patterns.
3) It would be nice to see the last move while trying to solve a problem. Sometimes, I dont have time to see which piece has been captured when I first start to solve a problem.
Thank you for a great program and keep up the good work!
