I second this. I've given Gosublime (and more recently VSCode) a solid try on several occassions. Neither hold a candle to the Intellij Go plugin. Being able to give solid rename refactor, and code navigation, even when your code is in a partial spaghetti, non-compiling-mid-development state is hard. And the Intellij plugin does a decent job at it. Not quite Java-level good. But pretty darn good.

The existing command line Go tooling (while great) just don't do a good job at providing that kind of support to your IDE.
