Appearance
Colour is in the material — the Materials tab on the left edge.
See-through, Floor grid and Snap are in the ring you get by holding on empty space.
Lighting - pick the type here. Hold two fingers still
anywhere, then slide with the other hand to aim it.

Models
Kept inside the app, no files involved. Your last
state is restored automatically when you come back.
Files
.glb, .gltf, .obj or .stl. A model comes back
as faces, not triangles, so it edits like something you built here.
For an .obj's colours, pick its .mtl at the same time.
