I use the remarks to note plant size at maturity, because I need to reflect that information with certain municipalities. Although the intended way to do that is probably with the checkboxes in the pop out to the right, I find that the way the plant size info prints out on the schedule takes up way too much space on plan and is unusable. That and the fact that I have the other dialog boxes used for other info makes my spec section slightly too long.
Not a huge deal, it'd just save a bit of time since I end up having to try one specification out and then click back into the dialog if its not the right one.
