Plugin to make Gedit use your theme's dark variant, just like Totem, Boxes or Eye of Gnome do.
Download and extract the ZIP into your plugin directory, usually located at
~/.local/share/gedit/plugins/, or clone the repository using git:
mkdir -p ~/.local/share/gedit/plugins
cd ~/.local/share/gedit/plugins
git clone https://github.com/fernzi/gedit-darktheme.gitThen restart gedit and activate the plugin on the preferences dialog.
