I think the program has everything in it like you are saying. We just don't understand it enough to take advantage of it. That was one of my reasons for changing the gravity number to 1.0 as that makes sense to us neophytes. I understand that under the hood it would have to be modified to the 40, but to a user, 1.0 makes some kind of sense without any explanation whereas 40 means nothing to anyone and just confuses us. Instead of looking for another feature to fix the problem, I went immediately to Gravity since I didn't understand why the number was 40. Now that it's been explained, I understand it, but you will have to explain this to every single user of the program where if you change it to 1.0 and to the math under the hood, it would not require any explanation.
