I have a fairly extensive (large) NR program running various things for my home control. There are 18 tabs and a significant amount of JS code. The flows_xxxxxxxxxxxxx.json file is 774Kb.

What I showed was the settings for a debug node in your flow. Simply edit the default "Debug xxxx" name and replace it with something more meaningful. Then, when it receives a message, the debug panel will have the name not just the reference ID. May save you having to always click the id simply to see where the debug came from.
