A menu bar app for Mac
Plug in your iPad and it lands on the wrong side. Again. Lineup lets you drag your screens into place from the menu bar, save the setups you use, and puts everything back the moment a screen reconnects.

What it does
Lineup keeps the arrangement for every combination of screens you use. When the iPad or monitor reconnects, everything goes straight back where you left it, with a quick note so you know.
Laptop on the left at the office, under the monitor at home? Save each one. Hover a preset in the menu to preview it, click to switch.
Turn Sidecar on and off with a switch right in the menu. No digging through Control Center, and it lands on the correct side every time.
