I have a rather large multi-tab flow. When I deploy, I get a warning that a specific const has already been defined. After a number of failed attempts to blindly stumble upon the problem I took the approach outlined in the reference above.
Since node-red distributes code across multiple nodes, it can be time consuming to track down specific source. It would be nice if the editor supported a built-in generic code search that identified tab(s) and node(s) location for the specific search pattern.
