About No-Metrics-Pane (slimmer DevTools)

Slimmer DevTools hides the "Metrics" panel in DevTools. For many developers, this box is rarely useful but takes up valuable space, allowing only a few CSS properties to be visible at a time. Slimmer DevTools removes it, letting you see more properties at once and work more efficiently. ### Enable/Disable To enable, open `DevTools (F12) > Experiments` and activate "Allow extensions to load custom stylesheets," then restart DevTools. To toggle Slimmer DevTools on or off, go to Chrome extensions and adjust as needed. ### Built for Simplicity Designed to reduce clutter in DevTools – inspired by this [StackOverflow thread](https://stackoverflow.com/questions/66691662/is-there-a-way-to-hide-the-box-model-graphic-in-chrome-developer-tools).
