I'd also like to see a boon that can remove previous negative "boons" from scenarios. Seriously, it's been over five years now. I'm sure someone could have removed that aggressive adware by now.
If possible, I'd like to see this at two levels. The lesser (and less expensive) version removes the boon in its entirety (lose the adware, but also the music files). The greater (and therefore more expensive) version removes the negative side effects, while letting you keep the benefits (remove the adware but keep the music files).
