This question follows on from this question. (Linux)
I am not asking how to change the background colour. Is it possible to change the theme of the GUI on the outside? It looks horrible having a light interface and dark notepad. I think a material dark theme would be really nice.
My question is short but I don't think anything else needs to be said. Please let me know otherwise. If someone experienced on this site could help me with which tags to use, that would be appreciated.
EDIT: progress
I am using this modified frontend.css in .Mathematica/Frontend/frontend.css currently
