Opening a new sketch doesn't replace the default empty window

Feature to enhance

Sketch window behavior on startup

Desired enhancement

When starting Processing and immediately opening a sketch (like an example or a recent sketch), the initial sketch window remains open even though it wasn't used.

When opening an existing sketch from the Examples browser or the File menu, the default empty sketch window (sketch_XXXXXa) should automatically close or be reused, instead of remaining open in the background.

Potential benefits

It makes the interface feel more intentional and avoids unnecessary windows.
