[Evolution] Remote content warning box

[Pete Biggs <pete biggs org uk>]

On Evolution 3.18.2

In 3.18 there was introduced a box that appears at the top of the
message to warn you about remote content not being downloaded.

I applaud the motives behind such a thing, but personally I find its
current incarnation too intrusive. It's almost as big as the headers
and pushes the mail down every time it appears - which is incredibly
off putting when dealing with lots of messages.

Is there any way of modifying this message box behaviour?

In future releases, might it be possible to find a more compact way of
doing the same thing?  What about at the bottom of the message instead
of the top?  Or using the area to the right of the grey header box
that's used for very little?
