The "Run Publishing Service Sync" button on the "Sync Schedule" tab REALLY needs a confirmation button to prevent full syncs from accidentally being executed.
This is useful because if you accidentally click this button when a Selective Sync is not enabled, you will unintentionally publish many updates and apps to your company.
Engineers would benefit from this.
When you click "Run Publishing Service Sync," a large confirmation button should appear that says, "Are you SURE you want to run a full sync? There are no selective sync options currently enabled."
