It would be nice to see at a glance, if a budget's rollover goes to a general pool, or to a category specific pool on the budget table. (This information is available by clicking into each category, but a visual marker, be it an icon, or some other distinguishing factor, would make it easier to see the information at the top level)
This also goes for what a budget's default behavior is each month, if it's a "fill to", "envelope", etc
