The next version is coming soon. It has the following features:
1. The ability to take single notes (a value can be displayed as a note)
2. The input pane becomes transparent when you move the mouse off it, and becomes solid when you move the mouse back over it. This way you can see what is under it if necessary.
3. Moved the Verify button to the options bar area. When you fill in the last value on the board, the final verification workflow begins automatically.
