I request that a button be added, similar to the "Hint" button, that shows valid moves. It used to be that the "Hint" button did this, but recently kpat has been changed so that "Hint" only shows the move suggested by the solver. It would be nice if the user had a second button, say called "Show moves", that shows all legal moves.
2nd this. First of all, I would like to note the significant improvement in the solver and congratulate the devs on the developement! However, I am afraid, this made the game unplayable. Now the Hint button just outright gives the solution, which basically defeats the entire purpose of the puzzle game :). The easiest solution is to roll back the Hint button functionality, to make it show all possible moves, instead of the "right" one (there can be multiple, thus quoting). I was gonna open a new bug, but saw this one already, so I simply adding to this one. Let me know is this should be reported in some other way..
