No problem, meanwhile I try Ultimate-Maia-Orange with Manjaro Budgie (Gnome). All works very good. Only one detail not: when you klick on the MENU button in the Budgie pannel the MENU icon gets blue background (when you hover it is grey). Can you change blue to grey? Do you know what I mean? - May 20 2019
Meanwhile I gave up Mint and tried on Manjaro XFCE and MX Linux (Xfce). Here you must replace some none-transparent border elements in the Ultimate-Maia xfwm4 folder to get windows almost like Maia. But the panel (dock) does not work fully: when you hover an icon in the panel then it gets white background. This is somewhen in the GTK-3.0 css file. But I am tired of searchng for days. ;-(. It seems that this theme really works only on GNOME desktops like Ubuntu Gnome or Solus Budgie. Can anybody help to customize it for Xfce desktips of of the box? Thx! - May 02 2019
The thema ist realy beautiful, It works for me for Solus Budgie, but not in Mint and MX Linux. The windows have borders and the windows dies not get the Maia look. I copied the thema normally in ~/.themes. I also tied /usr/share/themes. Waht am I doning wrong? - Apr 28 2019
