The About tab

The settings panel can show an About tab with the installed Earmark and Livewire versions, your limits, and optionally server details and a repository link.

Who can see it

By default it only appears in the local environment. Decide who sees it with a gate, much like Horizon and Telescope:

use Illuminate\Http\Request;
use Pixelworxio\Earmark\Earmark;

Earmark::about(fn (Request $request): bool => $request->user()?->isAdmin() === true);

When the tab is hidden, none of its details are sent to the browser.

What it shows

'about' => [
    'version' => null,          // override the version shown
    'repository' => null,       // an https:// link, or null for none
    'server_details' => true,   // PHP, Laravel and store
],

On a public site, turn off server_details so visitors see versions without details about your server.

Visitor settings (layout, position, appearance, saved views) are always available to everyone. The gate only controls the About tab.
