First, I would like to say I really enjoy using SSDT.
Recently, I was demonstrating its capabilities to people and received a relatively simple question after showing some Schema Comparison functionality. I showed how a person could save the definition of a schema comparison so they would not have to change the settings each time. The very simple question after the demo was, "Can you email me the results of that schema comparison?" to which I had to answer, "No." It never occurred to me to try emailing the results of a schema (or even data) comparison to someone to show to their management.
To be specific, the person did not want to save the resulting script that makes the changes; this functionality obviously exists. They wanted to save the interactive results page that displays all the changes, deletes, and adds.
Afterwards, I thought that would be a great idea. It would easily allow saving the results of a comparison so one would not have to execute the comparison every time someone wanted to see the results.
