A couple of days ago, thos wrote about the branding of the GNOME System Monitor; soon after that, a bug was opened about the image - how the colour was off for every non-blue theme, and how it went against the GNOME logo branding rules - and the image was removed. I liked the branding, though; and so did Luca Cavalli - so much, actually, that he wrote a patch for having the image coloured depending on the theme and with a full GNOME logo:
According to him, the patch still needs some clean ups, but I think now it would really be a great thing to have in the System Monitor for GNOME 2.18. Update@2007-01T09:44: the patch has been attached to bug #377144.
