The PS3 already lacks some of the functionality of the other versions. It lacks traditional hot bars, the inventory grid, and gil/seals display elements, all of which exist with the PC/PS4 version. It can only display a single log window onscreen at a time, where as the PC/PS4 can display each window individually. Originally it the PS3 lacked the focus target window. This was addressed with the 2.1 patch. When the focus target window is displayed, the experience bar and clock are hidden, I assume to free up memory the memory necessary to display the focus target window.
