Pinned Pages, a remarkable feature of ARC, offers the convenience of not closing tabs when a window is closed. This eliminates the need to manually close each tab individually with Cmd+W, which can be time-consuming and annoying.

One of the significant advantages of Pinned Pages is that they won't be cleared when a new window is opened. This allows you to easily switch between different tabs and windows, without worrying about losing your place.

Despite its numerous benefits, some users may experience slight frame drops and micro-stuttering when using this feature on devices like the M3 Pro. It's currently unknown whether this issue is limited to the M3 Pro or affects other devices as well.

In summary, Pinned Pages are an intelligent and convenient feature that streamlines your browsing experience, while also providing a more organized and clutter-free browsing interface.
