  Behavior Trees (BTs) got the robotics society attention not least thanks to
their modularity and reusability. The subtrees of BTs could be treated as
separate behaviors and therefore reused. We address the following research
question: do we exploit the full power of BT on these properties? We suggest to
generalise the idea of subtree reuse to "node templates" concept, which allows
to represent an arbitrary nodes collection. In addition, previously hardcoded
behaviors such as Node* and many Decorator nodes could be implemented in a
memory-based BT by node templates.
