Hi @mathishuettl,
I think you should look up this WordPress background processing class in GitHub

hi @sander27,
As much as I love to help you, helping with code is not possible . What you can do is you can find the relevant theme for your project which will give you the layout. And find the relevant plugin which will give you the functionality. If you feel stuck after doing that or have any other issue you can post it back.
Hi @chz516,
I`m discussing your issue on WordCamp Kathmandu Contributor’s day and would like to help you.
As I go through your issue description, unfortunately, I am having difficult to understand your problem. It would be great if you provide me the URL of that problem as well as a screenshot of the problem would be great.
