Panel: move pages

For a current project the client needs the ability to move subpages in the panel from one place/parent page to another. I know that this is currently not supported, but just to make sure that I don’t do unnecessary work, maybe some of you have already found a solution, or this function will be in the core in one of the next releases?

see here: Move Page Level

@jakobploens: Have you created a plugin that provides this functionality?
