Advanced UI Customization for Snap Assistant (Transparency & Themes)

First of all, thank you for this amazing extension!
I would like to suggest adding more visual customization options for the Snap Assistant (the layout selection window that appears at the top when dragging a window).
Proposed enhancements:

Liquid Glass / Acrylic Effect: Provide options for "liquid glass" style transparency (frosted glass) beyond the basic blur currently available.
Opacity Control: A slider to adjust the transparency level of the Snap Assistant background.
Theme Support: The ability to apply custom themes or colors specifically to this UI element to match custom GNOME setups.
Advanced Blur Tweaks: Even though blur exists, more granular control (brightness, noise, or saturation of the blurred area) would be a great addition.

Context:
As seen in the attached image, the Snap Assistant is a pretty grey even when blur is active. Making it more customizable would allow users to achieve a more cohesive look with other extensions like Blur My Shell.
