It could really use a way to control the spread of the button around the track ball. Just to make them closer together. The palmrest should also grow wider when columns are added to the keyboard.

Also, would be great to have an option of adding a USB hub on the inner edge for plugging in a USB key or adding a USB plug on the outside for a mouse.

On the advanced tab, you can adjust the vertical spacing of the thumb cluster to move keys closer together. As for USB hubs, at some point I need to draw a line and stop adding options. You can download a STEP file of the keyboard and edit it in CAD, or if you’re looking for something easier to learn, I recommend editing the STL file in tinkercad. If you don’t mind plugging in the mouse to the back, you can configure custom-sized connector cutouts in advanced mode.
