Years ago a member called SSWR made a bunch of small, yet effective, edit ideas. I didn’t manage to get hold of all of them before he took them offline, but there are some nice small ideas for ROTJ.
As far as ewoks are concerned - I like the idea that they are a thematic tool to take the rebels to the back door, and to act as a lure to the imperial forces.
It was joked around years ago that C3PO should be painted green perhaps - it seems oddly impractical to take a bright gold protocol droid to Endor when you’ve got the rest of the team wearing camouflage.
