Viewport authoring aids that set up Blender for 2D cutout work. None of them touch the .proscenio; they only change how the scene looks while you author it, so the whole panel is blender-only. It sits last in the sidebar and is collapsed by default. The panel currently holds a single tool, the Preview Camera.

Preview Camera creates an orthographic front camera framed the way the Godot importer expects, so what you see in the viewport matches the runtime framing. The camera is named Proscenio.PreviewCam: the first click adds it, looking down -Y at the Y=0 picture plane, and each later click re-focuses and re-sizes the existing one rather than spawning a second camera.

Its orthographic scale is derived from the scene, not guessed: the longer side of the render resolution divided by the scene's pixels-per-unit (the same ratio the Export subpanel sets). That ties the camera's visible extent to the export conversion, so a figure that fills the frame here fills the frame in Godot. Re-running after you change the render resolution or pixels-per-unit updates the scale to match.

The operator makes the preview camera the scene camera and selects it. Press Numpad 0 to look through it. It is undoable with Ctrl+Z.
