Well, it depends ;o)
First, what data should be included? i tried to transfer all (relevant?) information to the new cloud-tab. left out the count of children, just because you see them in the tree .. and the version is one click away in the details on the right (together w/ all the other properties)
Perhaps it's the easiest of you attach one sample here? Just format it, like it's the best for you (as dev) to work with and i'll try to generate it like that?
Second (you knew it, right? *g), copying to the Clip should be easy while using http://code.google.com/p/zeroclipboard/ . If the Browser does not support this, we could just show a Layer containing the Output so that the User could manually copy + paste it.
Ah, just to mention it .. the "Content Preview" as it's available in the old interface was dropped it .. i don't know if this is really helpful? Most of the Files are just showing the included License-Header, and even if they start with real content, it's truncated :/
