Actually, there are a number of community members and developers interested in progressing development work now it seems that Crowe isn't delivering (or communicating well... he's free to join in if he wants of course).
 
Discussions are ongoing and actions being planned to either develop the existing implementation, or fork the code and create a new 'community' client that can move forward.

The discussions are happening on the Telegram chat linked a few posts back. Others who are keen to contribute in terms of development, or other ways can feel free to join the chat.
