The theme.txt file is said to be somewhere in the the themes folder, which itself has to be in the Arduino folder in /lib or /usr/lib, but I cant find either of the files.

Where are the files located ?

Is there any other way to change the theme ?

If this is still relevant, you might be able to work with themes by changing GTK theming directly.
