Mistyping: Keys improvements

[GoogleCodeExporter]

I have been using your app v intensively these days, and overall I am really 
happy with it but for one problem: even with the "Bigger Keys" option on I find 
myself mistyping very frequently.. This is really frustrating in longer 
calculations (e.g. IRR) I always have to redo them to double check.

Some suggestions:
1) Zoom on the key being pressed just like the iPhone keyboard (another iPhone 
calc i use, Pcalc, is using this). The instant visual cue is a great help to 
prevent/correct mistyping. (and it would look much better than the current 
"whitish hue" key press feedback)
2) Make the keys even bigger? by removing the status bar and the grey frame 
surrounding the keyboard, you could save a little more space..
3) Enable users to "undo" the last key press by swiping the lcd screen (another 
feature of Pcalc). Unobtrusive and efficient.

Thanks!

Speaking from the perspective of another frequent user, PLEASE do NOT implement 
suggestion #1.  Zoomed keys is the most distracting thing ever, and one of the 
reasons I refuse to use products like Pcalc.

The most important update right now should be an iOS4/retina display resolution 
enhancement and iPad compatibility update, both of which are supposed to be 
imminent.  (Another useful update would be to run at "iPhone speed" instead of 
"1980s speed," though it's not as strictly necessary.)
