I took the numix-gtk-theme from Github, and began modifying it to make my own custom theme.
One thing that I've noticed, is that the custom theme only affects some of the Ubuntu windows. It seems that applications have their own window paneling, that I am unable to change.
gedit has the default Ubuntu buttons,
while the GNOME file manager is using my theme.
Is there a way I can get
gedit and other applications to match my existing theme? I want all the windows to look the same.
I am on Ubuntu 16.04 LTS, and have gone to the
gnome-flashback. I'm also using the
gnome-tweak-tool to apply the GTK+ theme.
It seems that I'm on GTK 3.0
(at least that's what I'm changing in the
numix theme to see relevant changes).
