In the recent update of Google Docs there is a new feature that I can’t find a good use for: when I print (download) the Spreadsheet in PDF, the file name now contains the name of the sheet as well as the name of the document. Until now the downloaded PDF contained only the name of the spreadsheet which was better for my use.
I hope they will make it an option.
On a related note, Spreadsheets still can’t remember print settings of a document – when the user closes the spreadsheet and opens it again, all print settings (i.e. selection, paper size or layout) are lost and have to be re-set again.
