The stormtroopers' animals.
All the cleanups, fixes, enhancements, remastering, restoration...
Kenobi's hut.
Cloud City.
Tractor beams.
Blast doors.
Fight expansions.
Removal of the cardboard "audience".
Vader's landing.
Numerous small expansions in too many scenes to be listed.
The Further Adventures of Oola.
Fett getting definitely, certainly, indubitably killed. This dull background noncharacter annoys me extremely; frankly I'd like the 2007 edition to have a scene of him getting dissolved by stomach acids, so that no Expanded Universe garbage could ever get away with resurrecting him.
More Tatooine.
Removal of the horrid Ewok song.
