Show indication on Nodes when logic is applied

When there is logic on a node and it is like retry or any logic, I think the node should have an indicator that there is logic applied. Whether that's the little retry logo, the little blue square, whatever it might be, because when you've got forty nodes on a canvas and maybe ten of those are LLM nodes that you want to put retry logic on, you can't retain the knowledge and understanding if you put it to all of them. You have to keep checking them all over again. It would be great if I could see exactly which ones I've already applied the logic to.
