Have the ability to export a file (or have it embedded in the log collection) that will be loaded into a standalone executable, which will present the UI like the customer sees it, instead of a GTM or asking the customer for the screenshot.
This will assist the support team to verify theories derived from the logs before getting back to the customer for verification.
For example - the support engineer suspects that there is an issue with the license provisioning but can't tell what is the configuration without looking at the customer UI. WIth the simulator, he will be able to check the configuration and advise on needed changes without a GTM or screenshots.
Also a good way to troubleshoot issues at dark sites if host names, IPs, etc. can be scrubbed out.
