[Evolution] Suggestion: Muted quotes (a la PAN)

[SpamBeGone <SpamBegone002 twilight-systems com>]

PAN has a nice feature - muted quotes.  It would be useful in Evolution I think.

Right-clicking on the message body presents a context menu with a checkbox named "Mute quoted text".  When this is checked, it collapses all quoted text in the message to a single line, displayed in a different color.

For example, this:

> This is some quoted text.  It's really fascinating 
> stuff, so I don't want it to simply disappear.  I'd
> rather just not see it unless I uncheck "Mute quoted
> text."  Because, life is too short to scroll through a
> message hunting around for the good stuff.  Why not
> let the message display take care of this little task 
> for you?  Ah, the wonders of technology.  Why, 
> it's such a contrast to the days of yore while I 
> was fighting in the Boer War.  It was hell. let me 
> tell you all about it...  blah blah blah...

...becomes this:

>  [quoted text muted]

It's handy to get it out of the way like that unless/until you want to see it.  It makes the Preview Pane more useful because you have to do less scrolling.
