What is a file shelf?
A file shelf is a temporary spot on screen where you drop files while you work, so you can pick them up again a moment later. It is a waiting area, not a storage place.
Why it matters
Moving a file between two windows is clumsy. You open two Finder windows, or stack things on the Desktop and clean up later. A shelf gives the file somewhere to wait while you open the next window.
How NotchStar does it
The Shelf tab in NotchStar has two zones side by side. The AirDrop zone sends whatever you drop on it. The shelf zone keeps what you drop for later. When you start dragging a file toward the notch, NotchStar notices and opens the Shelf tab by itself. If you let go somewhere else, it closes again.
What to know
The shelf remembers where a file is, not what is in it. It keeps references, so it stays small, and if you delete the file from disk it disappears from the shelf. The list clears when you quit the app. Because it is not a backup, do not treat a successful drop as having saved the file.
For text that should last longer, Quick Notes is a better home. For screenshots, the Screenshot Tray is a separate strip under the notch.
