This works very well! But I do have a feature request. If you see errors, you can check the project assets and see what's wrong and in what object. But if it's a list it would be handy if the popup could stay on top, so you can relink them all, without having to switch focus again to the popup. I handled this by resizing the main window, but a check/button to maintain top position would be perfect, like how it works in Irfanview.
