[dimitris chloupis]

Why using an operator is a problem ? looking into the recommended source code.

I'd suggest looking into randomize transform operator that does this
without using operators

I also implemented a gui with min max , for ?x,y,z axis to make randomisation more precise. Well keep testing, if randomisation exceeds boundaries of ground then the object will not drop on the ground which i think its normal behaviour, will also put a warning at the wiki
