Add a way to remove favourites if there isn't one already.
Do I really need to give a comment? I also suggest adding more hairstyles plus a colour pallet & doing what you need to fix the effects that can't use combos or backgrounds even if those features have to be disabled on them such as #1000.

Hi, select the favorite, tap the arrow at the bottom to bring up the top toolbar, tap the heart, and exit to the menu. The favorite should be gone.
I'm not sure why #1000 can't use backgrounds. I should be able to fix that. Which other effects can't use backgrounds?
Better color selection for backgrounds is coming.
