title: Add a custom command (with a custom icon)
body: <p>Is it possible in IntelliJ/WebStorm to add a custom icon somewhere in a toolbar that runs a custom command, e.g. CLI?</p>
  
  <p>If yes, is it also possible to add this in the projects .idea so that my team members also have this icon without any configuration?</p>
  
  <p>My goal is to add some custom Git commands.</p>
