I hated the constantly appearing wishes to buy wall speakers, so I made a mod to get rid of them. And since I'm likely not the only one who finds it annoying, I'll share it here.

This requires Showtime, and was made on the 1.69 patch. I imagine it would also work on earlier patches.

(A warning: the wishes won't necessarily disappear immediately in whatever household you last played, but either switching households or restarting the wishes via Debug Enabler will fix that.)
