The tray icon

TwoPlacePaste lives in the system tray on Windows and in the menu bar on macOS. The icon is a small clipboard that changes to show what the app is doing.

Icon	Meaning
	Connected to the relay and idle.
	Connecting — faded while the connection comes up.
	Uploading an entry (↑).
	Downloading an entry (↓).
	Both at once (⇅).
	Disconnected — struck through. It keeps retrying on its own.
	Not paired yet — faded and empty. Open the app to create or join a group.
	Needs a look — the ! badge. An automatic upload or download was held back by your size limit, or failed. It clears at the next sync or when you dismiss the notice in the app.

Hovering the icon shows the same state in words, after the group’s name — the name whoever runs the relay gave it. The app’s window shows that name in its title bar too.

The menu

Item	What it does
(status line)	The state above, in words.
Sync now	Syncs in whichever direction is newer — see Syncing.
Upload this clipboard / Download the latest	Appear for a few minutes after Sync now could not tell which way to go.
Open TwoPlacePaste	Opens the app in your browser. Starting the app again while it runs (from the Start menu, Launchpad or a double-click) does the same.
Check for updates…	Checks your update channel.
Quit	Stops the app. Nothing syncs until you start it again.

If the app cannot start its window — usually because its port is taken — the menu says TwoPlacePaste could not start, shows the reason, and offers Open the settings file… so you can change the port. See Troubleshooting.
