Thank you very much for the interest! ^_^
Currently the plugin do not have enable/disable option yet, but I do have a plan to add that. Maybe around holiday later on December-January hehe.
I was experimenting with shake intensity level (amplitude and frequency multipliers). But for some shake setups, the reduction in amplitude and frequency can drastically change the motion which could go against the developer intention.
Imagine the game trying to convey a motion for tornado spell, but the player reduced the intensity so it looks like a weird sway instead :(
So I decided against it for now.
I hope that helps! :D
