Often I have the following situation:
I use the small help numbers to find/solve the next field.
After that it would be nice if I could hide all the small help numbers entered so far and to continue without them.
If I need them again then I want to unhide them...
As a possible solution I would suggest to implement a long-press-event handler on the button to switch between big and small numbers to hide/unhide the small numbers. Or provide a popup menu to hide/unhide or to clear the small numbers.
