welcome on the Steem community and in @busy.org
we have many things in our roadmap and also tons of ideas. It's a nice initiative try to get community ideas
for now i would really see some improvment on the whole user experience including a gamification for the community effect, incentivizing participation in the platform,
a killer messenger system and app
other content type like video, live streaming, gallery system or easy photo nav for photography, product/service (for marketplace),
and a all in one platform is what we want to build with busy.org, allowing any developers to create an app that will be embedded in the busy platform and available for busy users. Just like Facebook Apps does. It will allow endless possibilities and opportunities for developers to create what they think is required in the busy platform and the steem ecosystem, without having to run and market their own domain/project
we also have to consider the incoming hardfork and enhancements like "communities" and more.. (check 2017 roadmap for Steem(it)

You're a talented designer and i'm sure you'll bring a lot of valuable contribution to our ecosystem.
Wish you the best.
