Warning for broken paths in Walkthrough
When working with Walkthroughs and reducing the number of scans the customer can see, it can easily happen that a Walkthrough path "breaks" when a required scan is removed. The problem is, I don't know that the scan is required for the Walkthrough until I remove it.
The time required for trial and error adds up quickly, even when using "st=xx". It would be very helpful if there were to be a Walkthrough path validation that would tell me if hiding a given scan position would break the Walkthrough.
