- I like the checkbox idea : turn them on to have control, off to stick to the original. Great
Of course, by default, all the boxes are unchecked.

- I really disagree on the %min + %max + randomness system: it's too many parameters.
I think we should have a closer look to the way statistical dispersion can be described.
A good way to deal with dispersion is to use the standard deviation number, which uses the same unit than the data.
The standard deviation could be the only parameter if we consider our clone objects properties being created under a normal distribution (Gaussian). The other parameter is the mean and is determined by the original object or the cursor position.

I personally think that only giving the standard deviation and using a normal distribution is enough for scaling / rotation / H / S / L / O. This really simplify the UI.

- For spacial scattering, as we said, we need more control on the distribution, that was your idea when you mentioned the 2 radius. There a many many statistical distribution possible. With a normal one the standard deviation is your radius, and 3 times the standard deviation is the scatter radius. If we want to control them intependantly we have to choose a more complex distribution, there are many out there :)

- I would get rid off the X and Y spacing and talk about normal and tangential scattering.

- I'm good for the tab system.  But what if you want all you shapes be controlled by the same randomness parameters ?
Maybe we should have a "Master" tab, to control all the items and dedicated tabs for each item.
