Comment 29 for bug 1085

This bug might be a good idea for improved UI

UI Refresh has become one of the goals to improve Thunderbird Adoption as desired by David A. From a decent UI, I expect that I can copy everything that looks like text, especially like in this case, where copying the headers (adresses etc.) could be higly beneficial in everyday scenarios like composing a new mail to a number of recipients from another mail without replying to that other mail.

On implementation, please allow mouse drag to highlight, highlighting across different headers (e.g. from AND cc) and keyboard highlighting using Shift.
