For diagnostic issue, you can use the default setup. There are also quite a few plugins that you can use to explore issues, e.g. [navigator.lua](https://github.com/ray-x/navigator.lua), [folke/lsp-trouble.nvim](https://github.com/folke/lsp-trouble.nvim). [Nvim-tree](https://github.com/kyazdani42/nvim-tree.lua) and [Bufferline](https://github.com/akinsho/nvim-bufferline.lua) also introduced lsp diagnostic hooks.
Also, you can do this: put **all** diag error/warning of your project in quickfix.

This will setup gopls with non default configure provided by go.nvim (Includes lspconfig default keymaps)
