Paste Switch has a small overlay that appears when I press the shortcut to cycle through recent clipboard items. The overlay should appear near the place where text is being inserted, not near the mouse pointer, not at the center of the screen, and not on the wrong display.
That sounds like a small UI detail. It was not.
The hard part is that macOS does not give every app the same accessibility shape. A native text field, a browser text area, and an Electron app can all look like “the current input,” but they may expose different Accessibility attributes. Some give an exact caret rectangle. Some only expose the frame of the focused text element. Some return stale or incomplete values depending on focus timing.
The final solution is not a single magic API. It is a small decision tree, backed by logs, with a clear boundary between “exact caret” and “good enough input box anchor.”
