Madrid-theme is totally configurable through its settings, from color palette configuration, to control over principal blocks width. This theme includes Dockbar Bubbles in blue tones. You can decide to use this Dockbar Bubbles or classic top-line dockbar only changing a theme setting.

Madrid-theme is totally open source, you can access to its GitHub repository, modify, redistribute or why not, contribute to improve it. All photos included are totally free by myself ;)
