That was also my impression when I read your emails while cooking
lunch today. ;-)

FWIW here are my expectations:
- Menu and keyboard shortcut do the same thing
- Senders in the message list: add to trace
- Implementors in the message list: add to trace (but is seldom
useful, only if you have previously deleted too many items from the
trace)
- Senders in the code editor: new window*
- Implementors in the code editor: add to trace
- Senders/Implementors Buttons: new window

*An exception could be if the selected selector is the selector of the
current method. Then it could make sense to add to the trace instead.
But I would not insist on that special case.

That the buttons behave differently than the menu items in the code
editor is actually inconsistent, but knowing that, I have become
accustomed to using them if I do want a new window. I would not be too
concerned if that would change though (then they should behave like
the actions in the code editor).

Kind regards,
Jakob
