Questions about the menu bar // Preguntas sobre la barra de menú

Tengo varias dudas sobre el programa para las que no he sido capaz de encontrar respuesta ni en la ayuda, ni en los foros. Utilizo Affinity Photo 1.6.6 en español para Mac y mis preguntas son para qué sirven:
- Ventana | Traer todo al frente
- Limpiar las ventanas flotantes | Preparado
- Vista | Mover al punto de vista anterior
- Vista | Mover al punto de vista siguiente
y en qué casos se pueden usar, ya que siempre encuentro esas opciones como "no seleccionables", excepto las de limpiar ventanas.
Muchas gracias por vuestro tiempo.

I have several questions about the program for which I have not been able to find an answer either in the help or in the forums. I use Affinity Photo 1.6.6 in Spanish for Mac and my questions are what they are for:
- Window | Bring everything to the front
- Clean floating windows | Prepared
- View | Move to the previous point of view
- View | Move to the next point of view
and in which cases they can be used, since I always find those options as "not selectable", except for those of cleaning windows.
Thank you very much for your time.

Some items are only for Separated mode (Modo separado) -- Acerca de los modos de espacio de trabajo

 

Some only work if there are 2 or more views (Nueva vista) -- Vista

 

Sorry for not replying in Spanish; this is the best I could do.

Thank you very much, I will review the links you have given me. And do not worry about answering me in English, it's enough that you take the trouble to answer.
