Add an option to adjust blur amount

[OJ7]

Is your feature request related to a problem? Please describe. I would like to be able to blur certain elements but to a certain amount so that they're partially visible.

Describe the solution you'd like An option to adjust blur amount (e.g. using a percentage).

Describe alternatives you've considered I was manually doing this using the Styler extension and just came about this extension. Here's the CSS I used:

._1Wn_k {
    color: transparent;
    text-shadow: 0 0 4px rgba(0,0,0,0.5);
}

._1Wn_k > span > img {
    filter: blur(4px)
}```
