I've just upgraded to U10.04 using the default (I think) Radiance theme. I'm slowly getting used to the new min/max/close icon positions.
However, in ThunderBird, the folder listing used to show folders in three different styles: bold black for folders with unread email in them, bold blue for folders with *new* unread email in them, and black (not bold) otherwise.
Now, in U10.04, the folders with new unread email are still bold but now in a light grey colour, making them far less prominent than the other two folder states despite being the most important.
(a) Is this just me? It could be something I've tweaked in the past and need to un-tweak (b) Any idea how to change this?
