I am using GoSublime with Sublime Text 3.
Often times in a large project I'd like to see the (function) caller's return arg types and while GoSublime enables me to "Go to" the declaration, that's still sub-optimal, compared to having an overlay that could just show up at the callee

So my recommendation is that you move to VSC and give away Sublime Text.
This is how it looks what you are looking in Visual Studio Code:
