Im not 100% sure this is ready to be shared yet but i figured why not? Ive only tested this on XFCE and have no idea how it looks on anything else.
Nothing super special here just my tweaked Materia Compact theme, I changed the accents to green for Manjaro and all the whites/blacks to shades of gray to make it easier on the eyes. It includes transparency but only a little bit and there are no window shadows if you use my compton settings.
Ive included the theme and my compton conf to make it look exactly as i intended. You may need to tweak the compton conf depending on if you have AMD or Nvidia (i have Nvidia).
Ive been tweaking it for a few days now and Ive likely missed things or could make some improvements. If you see anything thats real bad let me know. Ill tweak it as i find things id like to change.
Windows all look transparent in the screenshot but only the out of focus windows have slight transparency. The Icons used in the Screenshot are Paper Icons
Recommend the xcursor-breeze-neutral-git from AUR as the mouse cursor to complete the neutral/gray look if you want
