Maybe in the next version you can also add haptic feedback for calculator:

and more haptic from the F2thaK's theme.

PS: Where I can find file for the haptic feedback for the statusarea? (like the described above for calculator) (In certain application (like File Manager) there is no feedback for my status area, when I drop it down, while when touch it for send it up, there is feedback.)
