When you switch to a different Persona, a unique workspace layout containing the tools and panels used by that Persona is loaded. This may also change the menus available so that everything you need is at your fingertips.
To switch to a different Persona:
On the Toolbar, click the Persona button (Publisher, Designer or Photo) that you want to use.
From the Affinity Publisher menu, choose a Persona you wish to switch to.
In the File menu, select a Persona from the Personas option.
