At this point there are some small oddities:
- The timeline button SVG has broken hrefs. You can see it from the missing play/pause/rewind graphics.
- The Cesium InfoBox doesn't work.
This is probably due to a combination of:
- Running cesium from the local file system
- The VSCode/Electron webview or Cesium itself imposing sandboxing restrictions that breaks the InfoBox
Still, for the purposes of being able to quick and easily preview CZML content, this is a very nice starting point.
