title: Running 'goimports' on save in GoLand
body: <p>I'm using GoLand IDE to code in Go.
  When I save a file, I'd like that the unused imports disappear (like VS code)</p>
  
  <p>I have enable "Optimize imports" in "Code" -> "Show reformat file dialog". But when I save the file, imports it's still present</p>
