if you look at http://unitus.info/network you'll see it's very live. Network status is healthy and people are mining.

Regards any new developments, unfortunately there are no developers with spare time available at the moment. So unless anyone capable to develop and have any ideas to propose make an offer to community, there will not be much happening in near future in terms of development.

But we as a community are always capable to brainstorm about new features and other ideas which could be added to this coin.
