This is fun to play around with! A UI request - in testing different scenarios, I want to delete & retype the first digit or two only (what if I want 60000 per year? 75000 per year?) but deleting only the first digit empties the whole text box and I have to type out the zeros every time. Would be great to be able to edit only part of the many long numbers instead of the whole thing.
