The following facility was added to the version 7.2.1g of Hornet Windmill.

The Resource Spreadsheet has been extended to allow the current contents of the display to be saved to a utility file so that they may be recalled and the values recalculated at a later date. This facility will be useful for those users who regularly calculate the planned resource requirements, consolidating a series of resources into daily, weekly or monthly values. Once values have been recalculated the numeric values can be copied and pasted into your desktop spreadsheet application. The File menu on the Resource Spreadsheet has been extended with two new items: Save Worksheet and Load Worksheet; the new utility files have the extension .RWK.
