@jdick, what a great opportunity! I appreciate your willingness to open this up to others in the community who are interested in working on this design.
The first step is to form a UI Design squad who can focus on this widget and work in collaboration with the MF squad. @jecihjoy, I think this design squad can then provide the guidance you are looking for.
I suggest we use an upcoming Design Forum to talk about this new UI Design Squad - purpose, roles, communication, etc.
