It's been 4 months since the last communication from the developer, on this addon. After he took over, we were promised better communication, more updates and fixed issues.
Instead, we have nothing. Good suggestions are not being considered, questions about the addon are not responded to. Not even a single response in the thread is provided regarding the future of this addon, 2.2 compability, future features and so on.
At this time, avoid until he picks up and updates his course.
