UPDATED: Assimilate View Options v3.1
Assimilate View Options v3.1 re-creates a single selected playlist so its View Options (visible columns) are the same as the Music library (taking advantage of the fact that new playlists acquire the Music library's View Options).
This latest version worksaround iTunes 11's shuffle/song repeat difficulties which tripped an error when trying to re-apply those settings and prevented the script from completing properly.
