Save quality control (QC) which is in progress

How can I save quality control (QC) which is in progress, close index.html file and re-open it in the working status where I ended before? I do not see any “Save button” or something similar. When I close index.html file and re-open it, I loose the done work.

Thank you very much for raising that issue @rene.labounek. We’ve opened a ticket and will implement the feature once we agree on a good solution.
