I think it would be nice to have shell like history in Galculator Papper mode:
1. Put calculator to Pepper mode.
2. Place cursor is in Input field and run some calculations.
3. If cursor is still in Input field navigate through calculations history using Up and Down arrow keys, like it works in Linux shell.
