I want a money widget that:

– has individually editable fields for each digit
– has decimal digits (default to places for cents)
– has a currency label
– tap edits digit
– double tap edits all
– tap outside digit edits all
– swipe each digit
– swipe up increments
– swipe down decremenets
– rollover (eg 10) swipe increments next digit
– faster swipe increments faster
– keyboard entry edits all
– only keyboard inputs are numbers and decimal
– has configurable max/min
– has configurable step
– has +/- buttons that can simulate swipe
– can change currency symbol (and decimal digits)

the key feature is that it can be modified as either a single value or individual digits when it makes sense
