After scrambling of 3^5 and about 1100 twists I've found a piece with two s=
tickers of the same color. So there's some hidden bug inside the program :(=
- not all scrambled puzzles are solvable.

I'm pretty happy about the twist features too. In MC5D I relied heavily on=
commutators to make algorithms. I used the macro feature back then for se=
tup moves too: record the setup moves as a macro, perform the necessary alg=
orithm, then run setup macro in reverse. Your feature is then a stroke of =
genius, as only minimal effort is required to perform commutators and undo =
setup moves (as an aside, I believe ABinv(A) is called a conjugate). The p=
iece highlight feature is unusual, but it could be a pretty good way to imp=
lement piece finding. I won't know for certain how good it is until I prop=
erly use it, but it looks very promising. Personally I would keep the opti=
on to hide 1C pieces. I do see your point Anthony, but I always like to ha=
ve the option.
I found a bug in the macros feature, it seemed to mess up the twist count f=
or me, although that isn't a huge problem.
A great improvement over the last version, keep it up! :)
