Comment 2 for bug 429854

I've worked a bit on the code for this already. I found it was easy enough to enable copy for the threadpane, and to add something to the clipboard for each selected message.

That just leaves generating the header info to be added.

Is there already a function to generate a text summary of basic header info for a given message? Something like the table that's added to the top of all forward-inline messages, but as text with newlines instead of table rows.

If not, a suggestion of the best approach to this would be greatly appreciated! I could probably emulate a lot of the code forward-inline header table code, but maybe there's a better way.

Thanks :)
