I do wish they had the option to save the data server-side like FFXI had, so you could back them up before reinstalls and the like. (You can sort of do this if you're on PC by making a copy of your character data, but it's not exactly user friendly).
What am I reading? All you need to do is to load your bindings from the server if there is none present on the machine and then save them again on the server when you log out. The server doesn't give two shits about the order your buttons in your hotbars. At least it shouldn't and there is no benefits if it does.
