I would love to be able to highlight any chosen column. I have to check every day to see if any updates are due. I have a lot of columns and the column for the due dates is not in the front of the sheet (because there is other much more important info that we need to see first). it would be nice if i could highlight like you can in Excel and direct my attention immediately to that column.
It would also be nice to use a formula to highlight a cell with a date in it if it is that date or after.
