With AppManager open I edit the files of my project in an external editor, and save them. Then I go back to AppManager and press play or Cmd+R to redeploy and the changes are picked up and resent, but they are not updated in the UI. So for example I changed the background in the CSS file to #f0f and redeployed - it turns to pink but app.css in Itchpad keeps showing background color: #fff.
