So the units in Stack editor is not “files”, it’s “functions”(or “definitions”). And we navigate by functions, edit by functions, and finally program by functions. It’s more like the program is running and we got a call stack here. We edit the code that’s collected for a specific purpose without constantly switching the context. It can be faster. This is a very neat idea.
