For now, VSCode only will show the signature of the selected function. To see other function defines, we have to move cursor to make the selection. Is it possible to show all the function signatures like in GoLand?
This is now in VSCode:
It will be a huge help if gopls could also support this kind of completion hints like GoLand. There might be a performance hit, but we could make it a optional.

LSP 3.17 introduces the CompletionItemLabelDetails inside of CompletionItem interface, we can use this instead. I don't think gopls is currently using this field at all. Maybe worth doing the migration from detail to the label detail.

Today, gopls report function signature for completion items using detail, but the detail can only be rendered in vscode if being selected. However, the vscode render CompletionItemLabelDetails without being selected. I think it's a good place to hold the signature information.
