I think using keybinds is fine in some circumstances, but i usually have a lot of mods enabled and having a keybind for everything can be hard, I think it would be awesome if you could craft items that do what the keybinds do. An example would be an item called "ability one" (or something like that) that would cause you to use your devil fruits first ability in mouseclick. You could make one for all three abilities and the utility move, I feel like it would be more comfortable than using my right hand on my keyboard, especially because i still have to use the mouse to aim.
