Sloppy function design.
A problem with trying to sort tiles. To place the same shape tiles on a pile, to help with the sorting of them, the tiles fail to lock on top of each other, causing a mess of tiles, which are difficult to sort. Also, to move the pile of tiles in the column on the right, often a tile gets moved under the column and disappears from view. Need to move the image, which is being assembled, to find any tiles which have been hidden. These issues were not there with the previous version. I’ll keep looking for one that that is more user- friendly.
