Inform checkmates
Please have the chess engine inform the king has been checkmated when pressing the next move button. Currently, when the King has been checkmated, the engine needlessly tries to compute the next move and ends up displaying "error" message instead of informing user the White or Black King has been checkmated and no further moves are possible.
This has been completed! The “Calculate next move” button now changes to “Checkmate” or to “Check” when the opposing player is in check.

Chad Hendry. This ain't so. I just ran into a situation today 27Apr17, about 4:30pm wherein my Queen took a pawn, and white made a move d2d3 exposing the king to check. I moved my queen to capture the King but it was rejected, ha. Something smells fishy with stockfish, eh! I have all the moves written down.
