Skeleton
The project-wide armature picker and presence checks. The picker is the single source of truth the bind and automesh steps target; the body splits into subpanels.
Armature
A read-only list of every bone the writer would export, indented by depth with connected / relative flags. Click a bone to select it in the viewport. Inspection only - it never changes the .proscenio.
Pose Mode
Pose-only authoring shortcuts, all blender-only: Bake Current Pose keys every bone at the playhead (those keys do export), Toggle IK adds or removes a test IK constraint, and Save Pose to Library stores the pose as a Blender asset.
Quick Armature
A modal viewport tool that draws bones one press-drag at a time onto the Y=0 picture plane, without entering Edit Mode. The options box sets the front-ortho lock, chain default, name prefix, and grid snap. See the walkthrough for the full chord cheatsheet.
