It would be great to be able to filter on records where the value in the field was changed. Since you keep the information if the record history, it would be great to leverage this information in another way.
For example, I could have a used Toyota Prius priced at $9,999, and linked to this record I might have 3 leads.
At the end of the week I drop the price on a bunch of stock. The Prius could be $9,399 as a result.
If I could filter on the the price field with an option like '(Was changed within) | (the last 14 days)", my salespeople could then have a view of cars with reduced prices. They could then reach out to those old leads and try again with the new price point.
