Do you not have the correct screen top for this enclosure? She looks big and strong and I suspect she could push out of the top front corner where the plant stem is. (I believe you can order a replacement if yours is damaged or missing.)
Also, I'm not a fan of hot spots for Tokay. They are not desert animals that naturally have sun and shade/burrowing heat gradients of 50+ degrees. Tokay are tropical with heavy tropical forest canopy and filtered sunlight at best around them.
On the equator under the forest canopy, it's fairly even in temps and humidity, i.e., hot and muggy everywhere. It's all about ambient temps for Tokay. The only real gradient is between day and night time temps, and rainy and 'dry' season temps.
As for misting, I mean heavy misting, enough to provide water drops on surfaces for her to drink, will soak the paper towel. The paper towel will grow a funky pink and black mold if it does not dry out. I prefer Cyprus mulch to hold extra moisture that can me evaporated by placing half of that heat pad under the bottom of the enclosure. Since there is not a thermostat on that pad, you can slide more or less of the pad under the bottom to get to the ambient temp you are looking for. You could put the heat pad on a timer to turn off for a couple of hours, like midnight to 4 am, to drop the night time temps a bit.
This has three advantages. One, it evaporates the moisture more consistently from the wet mulch, and two, it creates a more even heat throughout the whole enclosure. (I've seen U-tube video of Tokay 'basking' under heat lamps. The only reason they are under the lamps is that the rest of the enclosure, especially in their hides is too COLD! But hey, we saw it on U-tube so it must be true???)
Third. You can usually spot clean the poop corner more easily by removing the droppings and the mulch in that spot. They like to use the front or sides a lot of times.
The point is that you can clean without disassembling any of the furniture every time. Every time you take out and put back all the tubes, bark and branches, Tokay are very stressed out. If your girl were about to lay eggs, or in the middle of clutches, she would stop laying because of all the commotion, sometimes for the rest of the season! Cyprus mulch can stay for months at a time without completely being changed or rotting.
I'd get bigger/wider tubes soon as well. She's getting big.
