FlowShelf is a lightweight, native macOS menu-bar app that gives you a temporary home for everything you collect today — copied text, links, screenshots, dragged files. It remembers them for 24 hours, keeps them a keystroke away, and clears itself so your Mac stays tidy. Pin anything you want to keep. No Electron. No cloud. No account. ~7 MB

Clipboard-fed drag-and-drop file shelf for macOS — copy in Finder or yazi, drag into Teams or Mail

A shelf in the corner of your screen. Invisible until you drag something at it. Free, native macOS, no permissions, no network.
