Thanks. You were right, there was no clear-all, and that was a real gap rather than a stylistic choice.
2.0.1 adds an AC key. It sits where `ans` used to be, bottom-right of the keypad next to the backspace key, and clears the entry, the result and any error in one press. Escape does the same from the keyboard.
`ans` still works, you just type it now rather than tapping a key, the keypad grid was full, and a clear-all seemed the more fundamental of the two.
