Transpose Plugin / Membership - Add To Shortlist plugin

Hi there,

I am looking for two pluggins for my website (wordpress)

  1. Transpose for guitar chords
  2. Membership plugin including add to shortlist/favourites which users can create collections. (https://themeforest.net is exactly what i try to describe. If you are a member, as a user you can create collections, bookmark any post)

Are there any suggestions?

Best Regards,
