Expected behavior 预期的功能

A hotkey for scaling algorithms methods swapping on the fly (if possible).

Good suggestion. This feature will made compare different effect algorithms more convenient in real time.

I think a simple way to implement this would be to add an optional key/value pair in ScaleModels.json. It could look like this: "hotkey": "CTRL+1"

It will take a lot of effort to implement this feature. I will investigate it after I finish the work at hand.
