I have a feedback for the PennyLane team. While I was diving deep inside PennyLane I noticed there was Barrier module absent. barrier() module is present within Qiskit and it helps a lot in visualisation and execution. I strongly think PennyLane should provide something similar to it.
Although, I acknowledge Barrier gate is not standard in Quantum Computing but it makes life a lot easier. (Barrier | IBM Quantum Documentation)
