Background: There are many great spreadsheets. Spreadsheets for creating quotes, for tracking orders, tracking kids learning to swim. But staff would rather use a good user interface, with buttons etc, than a spreadsheet when doing work day to day.<p>Examples: http://sheet.cellmaster.com.au/examples

It needs work.<p>Tag line: Web apps as simple as spreadsheets<p>Feedback welcome
