Hi David, yes, you.
The “Clean Tree” component is an example of wrong input ordering, which should be be avoided in GH V2 :
In most components, the main input (lists, trees) are found at the top, and the options are at the bottom of the input stack.
That’s why I hardly ever use the “Clean Tree” component without plugging it the wrong way at first and thinking " I should post about this in the forum some day".
That day has come.
