One Inspector. A clearer order.
Put identity and dimensions first. Keep colors inside the pane. Give Artwork and Scene the same compact, independent section headings.
A · Artwork
Properties → Palette → Layers
Drawing colors stay beside your artwork.
B · Scene
Properties → Layers → Selection
Document details lead when nothing is selected.
C · Scene with selection
Selection → Properties → Layers
The object you are editing stays prominent.
An unlabeled name above Width, Height and Total pixels. Frame-specific details and shared editing scope stay in Properties.
Composition and Selected layer keep their distinct meaning. Swatches scroll inside the pane; choosing a color updates the drawing-color preview.
Selection rises when active. Validation and recovery remain reachable as quiet disclosures. Scene uses its own layers and selection controls.
