The sort_array node currently only supports sorting a numeric array, it would be more useful to be able to wire in a key array, then the sorting can be performed by comparing elements in the key array and apply the changes back to the original array. This approach could make it easier to sort array of more complex data types or under more versatile conditions, like access array of vector based on their angles between a reference vector, or access geometry points based on certain property. 🙂
