It would be great if a group of products (or all products) could be increased/reduced in price for a specific customer group in bulk.
Example:
Business owner wants to increase all prices by 5% for all products for Price group 'A'.
Extra features for this might be that prices can be set to be rounded to the nearest dollar, nearest multiple of 5c, or dollar values get reduced a further cent to the nearest 99c value as some businesses like lowering the price below the dollar value.
Another extra feature may be that the prices can be rolled back, i.e. keep an automated backup of the previous prices which can be restored.
