As not being an english native, I have trouble deciding which version of this sentence is correct gramatically?
Grant special permissions to your employees to use different features of this program for a more streamline workflow.
or
Grant special permissions to your employees to use different features of this program for a more streamlined workflow.
When I read this sentence out loud, the version with the streamlined word sounds ok to me, but some of my friends and colleagues are saying that the correct form is with the streamline version, because streamlined would be in past tense.
