We've addressed this too by allowing a setup cell:

    ...

    with app.setup:
        import numpy as np
    
    @app.cell
    def cell_uses_np():
        # no np needed in signature
        result = np....

The best part about this pattern is that it enables "pure" (only dependent on setup cell) functions to be addressable:

    with app.setup:
        from typing import Optional, Any

    @app.function
    def my_fn(arg: Optional[Any]) -> Any:
        ...

but nice convergent design :) glad to see to see we're addressing pain points
