This is the Aurorae theme for Spectrum Maw Sit Sit. It is meant to be used with its Kvantum Theme. Includes an opaque version and a blur version. You can also use Breeze titlebars for the opaque version and select "Draw titlebar background gradient" for a similar appearance. Recommended configuration is to select either "No Side Borders" (better) or "No borders" (best).

The screenshots feature Luwx's Lightly Shaders Kwin Effect.
