Suggestion:
1)Do you planned to add substep scrambles (LL, MU, F2L etc.) I think it is great but not sure if it can be done.

2)For the mouse timer, I came up with a better(I hope so)idea just now: Adding an option so
i) Inspection disable on mouse timer
ii) Timer can be start with mouse timer without inspection
ii) If inspection needed, it can be start using spacebar, which can continue using it as normal
I think it is useful in case I want to practice algorithm on mouse timer(which doesn't need inspection) without going into setting and disable the inspection. And when I wanted to use with inspection, I just press spacebar. Same thing can also apply for Stackmat. Also I'm not sure if this can be done.
Another question, my timer settings reset to default itself. No idea what is happeningo_O
Thanks!
