Not yet. It requires TC 7 =))Did you tried FSE?
Well, you are an alpha tester, you write addons, you've already asked him once, and now I think you can formulate a request in such a way that Ghisler won't be able to resist =)) (if he actually reads it...).Why do you ask me?
BTW, the thing is that after you press F5/F6 on a "real" file in the "temppanel" wfx, the plugin should be able to call tc's internal copy/move function. Can this be done without majkihacks now?

BTW2: have you received my mail?
