## Description

Dimmer is a Chrome extension designed to reduce eye strain by dimming the brightness of web pages. Even if you use dark mode, bright images and videos can cause discomfort. This addon overlays a dark filter on the entire page, making viewing more comfortable.

Key features include toggling dim mode globally for all tabs or individually for the active tab via customizable keyboard shortcuts (Ctrl + Alt + N / Ctrl + Alt + B on Windows/Linux, ⌘ + ⌥ + N / ⌘ + ⌥ + B on Mac). Users can set sharing options so that dim states apply across all 'All tabs' set pages or only affect individual tabs. Default tab behaviors and switching between shared or individual dim states are also supported, ensuring flexibility tailored to your browsing habits.
