At some moment in past, the text above the arrows became truncated not to
exceed the length of the arrow itself. So in the current implementation, an
interesting part of the information (codec list in SIP messages, DTMF symbols
in RTP flows, ...?) is not shown if the arrow runs between directly adjacent
vertical lines representing communication endpoints. As the position of the
dashed lines is fixed, and also no "help bubble" appears when keeping the mouse
cursor above the arrow or text for a while, the only way to read the
information is to click the arrow and change focus to the main window and read
the information from packet list or packet dissection pane.
My enhancement suggestion is to return to the previous method, which I assume
was truncation of the text to the full width of the pane rather than to the
length of the arrow. There should be no risk of conflict with other text as
(intrinsically) no arrow ever shares its vertical position with any other one.
The positioning of the text should be as close to "symmetric over the arrow's
center" as possible so that the text would never be completely detached from
the arrow, and truncated from the right if necessary to fit to the pane width.
I don't think that moving the SDP contents to the "comment" pane and keeping
only the message name over the arrow would be a good idea, first because the
comment pane would become too crowded and second because everybody has been
already used to see the SDP etc. over the arrow together with the message name
and the application level address information (From:, To: contents) in the
Comment pane.
