Code navigation is extremely basic (can only find references in the same package!), often breaks, and can't handle stuff like finding all interfaces that a type implements, or finding all implementations of an interface.
Really good IDE support would include refactoring (more than renaming a local variable/struct field, e.g. Extract Function, extract parameter), advanced navigation/analysis (analyze data flow to/from variable, find call stack etc).
Go is somewhat decent in the tooling area, and you can get your job done with it, but it really doesn't have anything I would call good support in any area of tooling except the compiler (not code analysis, not debugging, not monitoring, not profiling, not package management).
I suppose it depends on what you're used to. I've never found myself wanting to do these things, but I'm also strictly from a Python and C++ background so my standards are admittedly lower than Java and C# people. Hopefully gopls solves for these problems.
Then, I tried VSCode with the Go plugin, both the default version and the go pls based one; and Emacs with the LSP package and go pls.
I can easily see it being tedious if you have to type every character.
