Shufflizer has been updated. There are no new features.
This version of Shufflizer was created with Angular 6. Some obsolete sections of code have been removed. All layouts have been changed from old style html tables to Angular flex-layout (previously it was a mish-mash of these two approaches).
Known issue
Playlist selection does not work on Safari/iPad when the user has enough playlists that the dropdown picklist needs to scroll. This seems to me to be an Angular Material bug. I am considering a more luxury playlist selection interface, and am motivated to make it a priority since it would address this known issue.
