Disney and Daron Nefcy: Bring Jackie and Janna Back in Season 4

This is terribly injustice, not showing Janna and Jackie in the show so much ever since Starcrushed, like not so much Jackie in the Season 3 intro and haven't shown in Mewni so she, Marco and Star could settle things and not showing Janna in the final battle with Heinous eventhough she was seen in the intro. We like to see more in Season 4. They are friends of Star and Marco too.
