Current controller support PC version of FFXIV is not that great and it really needs to be updated.

Support for controllers with back paddles/buttons, i simply would love to have ability to use my 8BitDo Pro 2 wired controller for Xbox back buttons for things like more ways to quickly access cross hotbars.

Support for PS4/5 controller speaker and touchpad features, yes i know there is settings to enable PS4/5 controller features but it dosen't work on PC version of FFXIV and of course have ability to use bluetooth connection when FFXIV is only game i currently know that PS4 controller bluetooth connection dosen't work at all.

Button layouts for Xbox One controller, Xbox Series X/S controller and Nintendo Switch controller when current Xbox 360, PS4 and PS5 controller layouts are simply not enough.
I know i could use any controller i like and then not pay attention to button layout but problem is, i don't always remember all button combinations to navigate in UI.

Gamepad customization settings to have image of controller based on button layout you are using and not just having image of Xbox 360 controller for all button layouts.

More options to customize button configuration.

Ability to set trigger activation range when not all controllers have same trigger activation range in FFXIV.

These are few things i would like see for better controller support on PC version of FFXIV.
