I want to present my new script for Maya: X-Ray Advanced.
Demonstration - https://youtu.be/lsqADYrmJU0
It allows you to toggle switch transparency on model by one hotkey and also to control a transparency value by hotkeys. It is very handy when you work with image plane, retopology etc.
I was inspired to create this script because of buggy work of maya x-ray (It turns off every time the geometry changes)
