I did some JS code refactoring, also implemented couple of features:

• Now workunit actions (download and upload) will retry on fail (instead of stop)
• Menu is hidden when calculations started, because tab change caused calculations to fail
• Favicon (couple of minutes in pixel art editor)
• Pause button
