New tail and shoulder suggestion

[uayten]

Hi, I don't know where exactly I could give suggestions about riggfy, but I heard on the CGDive channel that here is where the new types of bones are made and later inserted into the addon.

I'm a 3D artist and I don't know much about programming, but I'd like to make a suggestion for a new type of tail and also an automatic shoulder system.

I am attaching the file that I created the armatures.

1 - New tail rig type
1.1 The tail I created uses the Bendy Bones system, but with Start & End Handle set to "Tangent" on all bones.
1.2 I also created controllers that are parented to each other, so that the one closest to the base moves all the bones in sequence.
1.3 It would be interesting to put in Rigify, before generating the rig, an option to control how many bendy bones to make in each segmentation, if possible or perhaps to apply a rig type for each bone and select the number of bendy bones.

2 - New system of shoulders that move according to the positioning of the arm
2.1 When moving the arms up and forward, naturally the shoulders follow this movement, so I created a system to automate this movement.
2.2 I created a new armature(Rig Shoulder+) and added a bone for each arm that follows only the Z and Y axes of the metarig's elbow through "Bone Constraint: Copy Location (Y and Z)".
2.3 I copied the shoulder bone present in the metarig and past it to Rig Shoulder+.
2.4 Added drivers in shoulder rotation to track the bones that follow the elbow
2.5 Added more Constraints to be parented to the metarig's Chest
2.6 Lastly, I selected the metarig's shoulder and added a "Bone Constraint" to follow the movement of the bones of the Shoulder+ Rig.
To check the movimentation on blend flile, just move the IK hand to upper and to front.

I would also to inform that the modular skin system is very good and functional, but confusing at first, until today I couldn't understand how skin.glue works
