I recently stumbled upon the Jetbrains TV youtube channel specifically this one about Go [1]. I don't have Goland specifically but it's really nice that if you have a licensed Ultimate edition of the IDE, you get all that. I have been using IntelliJ for many years now (on a personal license)but pleasantly surprised how many nice/useful features are a key stroke away. Would recommend a quick watch.
