Humanity, and others redesigned to get a redmond like look. Needs to have humanity installed on your system.
The attached gtk2/3 theme is partially based on https://www.gnome-look.org/p/1313764/ . I took this theme and ported it to adwaita code base.
Atm its not fully finished but more than usable.
Do recommend you to use gtk3 nocsd if possible and to enable scrollbars.
0.8.1 : added a basic mimetypes folder, some minor tweaks
