Note Box for Excel Sheets
I would love for Excel to have a place for notes. A note box like PowerPoint has would be great for storing information about your data (where it came from, how you calculated it, notes to self, etc.)
I suggested a while back that some thing like this is needed to allow for better documentation of Excel files.
I want a post it note-reminder which is attached to the work sheet, and travels as I scroll. If the sheet is large it would be nice to have a reminder to enter an unpaid amount.
