Useful but cant delete entries

This app is very useful for tracking spending, but if you enter something my mistake, it wont allow you to simply delete it. You can zero out the expenditure, but it will show as "0.00". Also, the landscape overview doesnt give you a net (earning/spending) option. Itd be nice to too how much money you have left at the end of each pay period, as a budgeting tool.
