Kustom Breeze Enhanced

A spiced-up remix of Sierra Breeze Enhanced—now with extra usability, fresh button styles, and a bit of tastefully applied chaos.

🔧 Tweaks

• Clickable Corners & Edges ("Magic Corners")
  Fitts’s Law enjoyers, rejoice. The corners and edges are now hit targets, just like the Windows Start button or every theme that respects sanity. Breeze? Yes. BreezeEnhanced? Yes. SierraBreezeEnhanced had it—then someone thought it was a bug and axed it. I'm putting it back where it belongs.

• Opacity-based Titlebar text (Window title/caption) color
  Tailored for translucent themes: The window title now picks up just a hint of background color. It’s subtle, it’s slick, and it keeps the caption from looking like it’s floating in a void.

• Darker titlebar - #121212
  To blend with my Zephyr Kvantum dark theme. Combined with a matched opacity drop (to offset Kvantum’s opacity values), it pulls off that clean, frameless aesthetic we all love.

✨ New Button Styles

• Plasma
  The classic, reimagined with flair. The buttons now glow to full opacity on hover. And for the 'Always on top' button, added a custom hollow/filled dot that looks right at home in the titlebar.
• Mac Mono
  A monochrome version of the macOS Sierra theme. And they also are opacity-based so doesn't look out of place in a translucent theme. The 'Always on top' here is only visible on hover/active as mac themes look better with the traditional 3 button setup.
• Zephyr
  My original flavor. Originally lived in a personal fork of BreezeEnhanced called Zephyr. That got borked by KDecoration3, so I gave it a new home here. Now with all the new SBE goodness baked in.

Rest all of the existing goodness from SBE remains 🌈

⚙️ Installation

After installing, you’ll need to restart KWin for the decoration to show up:

On X11: run kwin_x11 --replace On Wayland: run kwin_wayland --replace

You can run that from KRunner (Alt+Space or Alt+F2), or just log out and back in like it's 2005. Once that’s done, you’ll find Sierra Breeze Enhanced in: System Settings → Colors & Themes → Window Decorations
