New version! Is this version the "Snow Leopard" of GC-BTT?
In seriousness, I think I've got performance to an acceptable level. I'm now seeing some of the lowest energy usage from the preset in a long time on my system. Things also just feel much, much snappier as a result.
EDIT: After a few hours monitoring BTT, I'm really happy with the performance of this version. Honestly, if I wasn't the one who made the changes, I would've guessed that I increased the refresh rate of the scripts because of the sheer performance boost.
Please report on how performance of this version is on your machine so I can make final adjustments! Thanks everyone

- Some lighter-colored dock widgets like FaceTime might have black text instead of white. If so, then that's an import bug @Andreas_Hegenberg
