Here are some notes.
Please let me know if you are interested in this feature, you are interested in helping code, or interested in testing this after some alpha or beta code is developed. Please do not send PM regarding interest. I'd like to keep this open to the community.
However, I am not a developer. If you are a developer and interested in a free community add-on with this feature then please let me know. Maybe you have some ideas on getting this project kickstarted.
