Nice and easy but...

Nice and very simple calculator. Here, we have 2 taxes (provincial and federal as Tax1 and Tax2 for example) and this would be very very useful to have this on this calculator. Perhaps an add-on for later? 3 and 4 digits setting will be also appreciated (not only 2 digits). Sound with a mid level ...

Another point, I dont know if its me or my phone (3GS), but keys are not so fast. When I press on the key, I have to wait half a second each time... Perhaps increase a little bit this would be perfect.
