Tooltips in Konqueror and KOrganizer are amazing. Why not introduce them
for threads in KMail (and KNode)?

I don't think IBM proposition of placing in tooltip 'line representing
message content' because:
    - how determine that line?
    - first - encourages top-posting which is Bad(tm)
    - first non-quote - not necessarily most important, may be
      misleading

But information about author, date, maybe change of subject, status
flags(?), would be very nice.

How it should like?

Note: (was: My ideas) is real addition, not KMail modification

With more than X messages in thread, in tooltip should be only
X messages and cut could be shown with eg. ellipsis:

Cut should be determined not only by how thread is long but with
sensible indent estimation.
