Sadly, I don't have time to work actively on the project, I can answer questions, but I am not going to develop any major change. If you want to contribute as developer I can help you to get started with the project. Just ping me.
Thanks a lot to Barbara Ramiro and David for their suggestions, I will try to improve everything you said.
I have received several emails asking why Archaius doesn't work on Moodle 3.2. The quick answer is: it does. you just have to install the base theme (https://moodle.org/plugins/theme_base), I think I am going to remove that dependency to avoid problems in the future.
