I see your point.  Showing Debian-specific upgrades differently from
upstream ones might certainly give some users the wrong impression about
Debian-specific upgrades being more or less important.

I guess it might be possible to carefully choose slightly different
colors so that neither one of them looks obviously "more important" or
"better" etc., to try to ameliorate this... but probably the better
solution is to make the distinction optional and turned off by default,
as you suggested.

I'm not sure if this is what you meant, but I don't think the particular
UI change implemented by this patch is possible to implement using
themes, since I had to add a new style (which means I should have edited
whatever generates this documentation too... oops).

I probably wouldn't use a tree-based version of this either -- I found
it to be the most useful in the Preview pane, where there are no trees.

Thanks again for your feedback!
