Hello,
I am the author of Queue and am interested in the problem you’re having. All the extensions appear to be loading on my connection right now. If i read your comment correctly you don’t specifically have a problem with queue, just stating you have not populated it with content, however you can’t load content/interact with any of the panels?
In developing extensions I did find that on some odd occasions that extensions outline would be shown but they do not render. This was true even after refreshing. I can not say if it was due to a CDN issue or the javascript’s extension watchdog ‘supervisor’ which i saw throw errors some times.
I find in these cases having F12/DevTools window open and watch console errors and network traffic to try figure out whats going on.
If I misunderstood your comment and there is an issue with queue directly, please create a ticket on the github project page either through the configuration panel or https://github.com/Serivy/StreamTheory/issues if its not loading.
Cheers
