I'd like to see the random also have included a box that you can select that says:
"Allow Back-to-Back". When not checked, the next random number will not be the same as the previous. So if the random INT picked 5, then the very next time it can not pick 5. The same number would not be picked back to back. So maybe it would store it in a variable and would look to see what the last variable was or something. Not really usefull for floats, but intergers, yeah.
So yeah, it's not completely random, but then again what is? Would be a cool addition.
