I use offset too, but it's a really obscure filter and a lot of people don't know about it.
Nothing obscure about it at all! All it does is move pixels in your input amounts. It's also useful for spacing things out evenly, for example if I draw a vertical line and I want to nudge it 12 pixels to the right on my canvas, I select the line layer>offset filter>horizontal +12px. It's a very simple filter. What makes it useful for texture tiling is whatever is pushed off the canvas is pushed back on on the opposite side, so if you offset the image in both vertical and horizontal directions in exactly %50 of the image size (256px of a 512px image) anything on the outside of the image is offset into the very center, and thus exposing the seam.
