So how do you handle the scenario where one tool might have 20 Atoms on it,
but the next iteration of that tool will have 1000? Do you simply just add
new controls to the pool if needed allowing it to grow to the max size
needed? Then when they are no longer needed, just set the parent to null? If
I can't get what I am working on to solve the problem, I will look into your
solution.
Thanks,
Jim
