How to hide the left half of the keypad and use only the simple (enlarged) right part?

[pstein]

In general I use in 99% of all cases only the keys on the right part of the keypad.
How can hide the left part (starting with MS, MC, MR,... and ending with + % m left+right arrow)?

The space of the left part should be used to automatically enlarge the keys on the right side.
This would help users to reduce necessary concentration on positioning and clicking the cursor on the correct key.

Deactivate always "Always Show Number Pad", and select "Number Pad" in the keypad type list, in the keypad menu (using second button from the right in the toolbar, or the context menu of the keypad title bar).
