On my 8X I ended up with a "jewel" on register switches 1, 5, 10, and 14. One could do away with 1 and 14, but I think it keeps the look a bit more symmetrical. This arrangement lets me find the proper registers easily, even with my fading eyesight. Nice thing about the dollar store "jewels" is that they pop off very easily without leaving any (or little) residue. I find too many colors too distracting, so have just used a nice blue on all 4 marked buttons.
