Admin UI in Elixir is easy with some popular libraries 
We kinda do get a roadmap with Elixir and Phoenix as both José and Chris often share what’s coming - not sure if there’s an official roadmap anywhere tho. It’s usually done in conference keynotes 
Perhaps you could add ‘News/updates’ in the community section too? José and Chris do a great job of keeping everyone informed with updates 
(Not related to Elixir but I would say documentation and guides for Rails are excellent as are Ruby docs.)
