you dont say anything about a running wheel.
IF you dont have one, I'd spend $40 (specially since you are getting a second one)
and get a freedom wheel.

It may take her awhile to start using it, she could start right away, or even not use it. But its seems to be fun for most of my gliders.
I have some small cups in our cage, foraging cups. I would put a few in different areas of the cage, put maybe HALF a treat in each every other night, and let her search for treats in the cups. I would use dried mealworm or yogurt drops. if she has a favorite healthy food "peas" you could put that in the cup.

the shopkins we got at walmart are nice foraging cups.
get a feather, play with her like a cat, some gliders love going after a feather.
change up her cage, ?get a bigger cage? move around toys or add toys.
we get kids toys from store and they like exploring or hanging out in them.
have an out of cage place, let her out to run around and explore, make the out of cage place glider safe.
