Thanks for the info, it is indeed very helpful and does what i wanted, however i consider this to be a workaround. I was looking for something that removes Users from Schema Comparison permanently. What you are describing is a procedure that has to be performed manually for every new comparison that is done.

It might be better to have those filters in a new tab in the Comparison Properties (named "What to compare"), where the user could define them once and then "Save as defaults", much like what is done for the Options part of both the Schema and Data Comparison windows. That could also filter the respective options in the existing Filters window.
