A simple way to change GTK 3.0 themes when light mode or dark mode is toggled. This does not handle switching between light and dark mode based on the time- that requires the usage of Night Theme Switcher instead.
At the moment, it has only been tested with GNOME 43, but it should work with GNOME 42 as well.
Tar packages and an extension page are not available yet.
The source can be used by cloning this repository and running the install script like so:
git clone https://github.com/CharlieQLe/gnome-extension-gtk3-theme-switcher.git
sh install.sh
After the installation, simply log out and log back in and it should show up in the Extensions application!
