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.
