Thanks for your posting. It would be possible to implement this (e.g. refreshing the page based on an interval) but we don’t recommend this as this might refresh the page while the user is actively using it (for example, while adding a test result or reading a test description). I’m happy to add this to our feature request though and we will make sure to look into this for a future version.
If you frequently have many users working on the same test run, you can assign different areas of this test run to different users (distributing the load) so that those users can work independently.
