When I change the priority of my thread, nothing happens and it is still displayed in the same color as threads with "normal" priority.
Bold and Italic works fine.
Where is the problem?
The problem is the "style.css" of your Nuke-Theme.
It filters the color-informations of the priority-setting.
So please modify the "style.css" you can find in your themes directory or use a different theme if you would like to use priority-settings for threads.
