binding enabled+hidden

[marcinpiotrsobczyk]

It is possible to override DOMNode.check_action.
Docstring:
"""Check whether an action is enabled.

    Implement this method to add logic for [dynamic actions](/guide/actions#dynamic-actions) / bindings.

    Args:
        action: The name of an action.
        parameters: A tuple of any action parameters.

    Returns:
        `True` if the action is enabled+visible,
            `False` if the action is disabled+hidden,
            `None` if the action is disabled+visible (grayed out in footer)
    """

So the possible states are:

enabled + visible

disabled + hidden

disabled + visible

Is it possible to have enabled + hidden? We can use show=False but its global configuration, with check_action we can have configuration depending on screen type. Basicly I want to have on one screen binding enabled + visible and on other is enabled + hidden.

Rather than using check_action, perhaps you could simply define the same binding on the other screen with show=false?
