Not exactly - as I was saying, in Classic mode you cannot change to another Profile or Activity.
Yes, you can, i do it all the time. There is a shortcut that you can place in the main menu, it gives you the option to choose another profile. Or you create your own shortcut that with one click switches directly to the profile of your choice.
I don't remember exactly where i found that already existing schortcut, somewhere in the drawer or you can add it when you are in the drawer, from there you place it in the main menu.
