Version: 3.5.6 (using KDE KDE 3.5.8) Installed from: FreeBSD Ports OS: FreeBSD In KDE, active tab has a top border that is the same color as the system default color (blue by default). I think it would be interesting to be able to change the color of the top border of this tab, as some people like it to be different to show the tab is active. For instance active tab could have an orange top border, while the rest of the desktop would still be blue. This is just a suggestion.
Which style are you using? plastik?
Yes, Plastik and Lipstik.
Plastik (the KDE3 style) is no longer maintained. Oxygen's tabs do not a separate highlight color for active tabs either, so this issue is not relevant to Oxygen.
