The Footer in Palo Alto has customizable elements in the form of section blocks. You can add in blocks by clicking the small arrow icon next to the Footer section then clicking the 'Add block' buttons:
Other than the individual blocks, the Footer section also has a number of settings itself. You can set the background and text color, disable the footer wave style or set a different color for it.
There is also the option to show payment icons, currency, and language selectors, as well as a short menu in the Bottom bar.
