body: <p>How to set Electron Browser Window DevTools width?
  I know how to set width and height of the mainwindow and open DevTools:</p>
  <pre><code>  mainWindow = new BrowserWindow({width: 1920, height: 1080} 
    // Open the DevTools.
    mainWindow.webContents.openDevTools()
  </code></pre>
  <p>But I would like to set DevTools dock width somehow, is it possible? Or set &quot;Body&quot; width so it leaves space for DevTools, setting width style does not help.</p>
