Lightroom CC: Ability to view photos in Fullscreen (win)

I'm trying out the all new and shiny Lightroom CC on my Windows based Convertible (Acer Switch Alpha 12). The first thing I'm missing after a few minutes is that there seems no way to just view a picture in fullscreen (like the "F" shortcut in Lightroom Classic CC). 

Is there any timeline when this (basic) feature will be available?
