I played on PS3 until the PS4 version came out, and at that time SE created a feature that let us upload our character settings, gear sets, hotbars, macros, etc. (though not system settings or HUD Layout, which might conceivably be different between platforms) from a PS3 and then download them onto a PS4. I keep wishing they'd revive that system but make it omni-directional, so we could upload from any platform and download to any other platform.
(The original had the upload feature exclusive to PS3 and the download feature exclusive to PS4, so we could only go one direction with it.)
