The coolbars on all Kepler RCP applications look just terrible. This a project created from scratch on Windows 8.
What is it with that thick black line sorrounding the coolbar?
Can it be style-hacked with CSS?
From my testing, it seems that it appears only when the perspective bar is present.
I think the CSS for this is the eclipse-perspective-keyline-color
in the #PerspectiveSwitcher
selector.
