I was making a cherry toy chest for my grandson. The front, sides, and top were all rail and stile construction, for which I used my Domino, noting how quick, easy, and accurately it let me join the parts. I was next going to use the domino to join the sides to the front and back, which meant domino mortises in the "fronts" and "rears" of the side pieces, with mortises in the "backs" and "fronts" of the front and rear stiles. I was thinking how quickly and accurately I had cut five mortises on the stile on one side of a "front" piece, when I realized that I had cut them on the side, rather than on the rear of the stile. Whoops... While trying to figure out whether I was going to try to fill the holes, or make an entirely new front piece, I realized that all I needed to do was to lay a rail along the seam between the (incorrectly mortised) stile and the two rails it was already glued to, and run my TS-55 up the seam, neatly cutting through the joints. I only had to cut and join a new stile.
