Hi Dennis,
having a positive gravity number for hairs falling toward the -Y axis would have been more accurate, more "realistic".
But it's your choice after all, and as soon as we know how to deal with that parameter, it's not a big problem
And I can't really help you with another word for "gravity" because english is not the language I use everyday
Just one little thing I've noticed : when you manually change (with the keyboard) the number for "stands per unit" and then hit "enter" (with "real time" checkbox checked), nothing happens. You have to click on the up/down little arrow near the field to really make the change in real time.
Probably that the same problem occurs with the other fields.
But this is not a big issue 8)
