Limit Break Button

You could probably map it to any USB connected object, like a toaster, if you were motivated enough.

This could be very easily done, assuming you can set a keybind specifically for Limit Break (rather than assigned to a hotbar button). It's like how Elite Dangerous has all these firegroups available (consider them hotbars). But certain functions can be mapped either to the firegroup (and you cycle firegroups to reach them), or you can bind a specific button to it. I have this specific hotkey set up for Shield Cell Banks, Heat Sinks, Chaff, and Electronic Countermeasure (on my HOTAS). If I could do something similar in FFXIV for Limit Break, I would get a USB device that is just a big red button and program it to cast LB when hit.

Even if you can't do that, it can be done (big red button for LB), but it's a little more finicky.
