MUI 5 Black Green Rounded Button Modern Look
Highly a screenshot, but it's fully possible to get a really modern look out of MUI5 under AmigaOS 4.1 Final Edition Update 2 Hotfix and Enhancer 2, even that AmigaOS is not based on the Ambient that MorphOS uses.
Screenshot shows a heavy customized, advanced MUI5 configuration with rounded buttons and sliders, all in black and green. The others functions of MUI use other colours for the text, while the background remains in same shape as my overall MUI look.
Hope somebody will develop alternative themes to use in MUI5 for AmigaOS4 and AmigaOS3.
