This might have already been covered, but I have not found it. Is it possible to edit my playlist? It's become very long and I need to prune it back and get rid of the quizzes that are superfluous.
Another feature of these playlists that would be helpful is if we could create macro categories for them and then lodge minor categories beneath. So for Geo, I could list bodies of water, mountains, captial cities, etc.
Yes you can, simply click on the playlist you wish to edit. When you are on the page of the playlist you wish to edit, (example) below the name of the playlist, there should be a blue 'Edit' button and you can click on it.
I hope I helped ;)
