Feature Request Description

On OLED monitors, a great option to have is a pure black theme with #000 as background and #888 as text. A way to dim the Favicon in the upper tabs. And a dedicated control for image brightness.

Currently I use the following CSS in dynamic theme editor to control image brightness. It works very well. Although I have to keep applying the theme every time the browser is restarted. When it comes to Video my personal preference is to play video content using their original brightness.

Dark Reader Version 4.9.96, updated a few days ago.
Linux Brave Browser
[Version 1.64.113 Chromium: 123.0.6312.86 (Official Build) (64-bit)

img {
filter: brightness(0.5) !important;
transition: filter 1s linear;
transition-delay: 200ms;
}
img:hover {
filter: brightness(1.0) !important;
transition: filter 1s;
}

It would also be great if Darkreader can modify the brightness of Favicons in at least the upper tabs of the browser. Currently I have to use a separate extension for this called Tab Modifier.
