-Figure 2: With ortholinear layout, it is easy to use the same PCB but omit keys

-![TrackPoint breakaway](23.gif)
-
-Figure 3: In this example, I chose to have the left TrackPoint button attached
-to the left half and the others attached to the right half using PCB
-breakaways. Then the split halves can be pushed together to fit in the laptop.
-For only desktop use, one might choose to keep all 6 thumb keys.

 Layout can be mapped as desired with QMK.
 
-Planning to offer other layout in the future for those who don't want ortho.
+Other physical layouts will be offered if there is enough demand for them.
