YES! It is easy!
In carouselSmall.xc, I had previously adjusted the alpha of the 'favorite' mark to about 60. That worked, but was ugly.
I'd seen that there was a "layer" command for the background, but only "substrate" was used. I didn't know I could use the simple setting of "top".
It's fixed now. I'll let Aslain know, so that he can add the command to the main modpack.
Thank you much, "Nekromant"
