The ability to sort any table view by one column and then by another. Three levels of sorting would probably be sufficient for almost any use-case.
1st level - sort by column for Deal Stage
2nd level - then sort by column for Deal Amount
3rd level - then sort by column for .....
The value would be to be able to see data exactly in the order in which you want to see it. I know Salesforce and Excel have this feature.
