Add Dynamic Transparency to GNOME Shell’s Top Bar With This Extension
One feature GNOME users have always wanted is a transparent GNOME top panel – but it looks a little displaced when as a maximized window.
Dynamic TopBar is a small useful extension for the GNOME Shell desktop that “makes the top bar transparent when no window is maximized.”
When its color turns black (or whatever color your default GNOME Shell theme is, it styles the background-color property of the panel without using an image file).
You can customize the degree of transparency through the extension’s preferences setting and you can choose whether you want a button shadow or not.
It’s not a revolutionary change but it sure is a neat one. The app shelf on Chrome OS does something similar as it makes the top panel transparent when no window is maximized and solid black when one is.
The ultimate things is that it is clean, quick, and effective.
