When using the Set Regarding for emails, we more often than not find ourselves wanting to drill down to Opportunities, then Change View and then select My Open Opportunities. Each user does this dozens and dozens of times a day. It would save a tremendous amount of clicks if we had an option to set a default search to a desired Entity and View. With option of course to overwrite that when necessary.

Also having it behave like a Global Search makes for a very slow experience.
