Premoves finished! My premoves are now fully implemented and the branch is merged. Making the move with middle click removes that specific premove. Middle clicking a random square clears all premoves and arrows. I also added principal variation search (pvs) which is just searching moves that aren’t the previous best move with a tight move score boundary then researching them normally if they are better than expected. I am probably going to ship soon and so will start polishing the project up now.
