So, first of all thanks @the5minfilms for trying out Blender and especially my Add-On 
. If you have already any findings and / or suggestions… more than happy to hear them.
For sure I am a bit biased just because I am playing around with Blender 'n stuff for quite some time already. However, I am not so sure that “floating limbs” make animating easier. Sometimes I even think the opposite is the case. Where limbs are not directly connected to the body you cannot use this connection point as a “pivor” or “anchor”. If you animate this body parts, you have to pay attention that they move some kind of realistic. E.g. with the arms you need to move the shoulder in addition, otherwise it just looks strange and not right. Now as those two parts are not directly “linked” in the model, you have to remember. On the other hand I feel it not more difficult to animate limbs with a direct connection. It might take a bit away the “freedom” to animate as you want but it also offers some kind of guidance. Just my thoughts on that topic.
A community mod would be for sure something nice. Especially if it would be not only open but also well documented. This could work as some kind of tutorial for new modders where they can contribute and understand the basics. I am quite sure that each mod can count on some support from the community… at least in giving advices and sharing experience .
