I am explicitly calling encodeRestorableState (in windowWillClose) and restoreStateWithCoder (in windowDidLoad), storing and reading the data to/from a file myself. I know those are normally used as part of the automatic app state restoration, but I want to restore a window's state regardless of whether it was open when the application last quit.
I'm using encode/restoreState because it's an existing mechanism that seems to suit my needs, and aside from this first responder thing it's working fine. Also, I'm assuming - though I haven't tested this yet and the docs don't say - that the window state restoration will take into account changes in the monitor configuration, ensuring that the window is restored to a location that is still on screen. If there's a better way to do that I'm open to it.
