Hello, people!
I've announced earlier that the eOS theme would be on Github for any brave should to help update it, unfortunately no one came forward. I've received one note about an effort being made, while I thank that person for trying it wasn't enough to keep it updated.
Now !zagortenay333 (https://www.deviantart.com/zagortenay333) has taken that job and already released it:
Any future updates will be provided by him only.
