[Feature request] controlling the shake with a number from 0 - 100

[chibbi]

Hi, so i like that you can deactivate the shake if it bothers you, but i think it would be perfect if you could control the shake how much the screen should be shaken.

I also think, being able to control the size of the other things, could be helpful.

I am wondering if sometihng like that is already in the works or if there are some limitations preventing that or if that could just be added.
