Great plugin! I am very happy with it.
A suggestion: I always need to go into your js file to move the spinning wheel away from my "enter" icon because it always ends up right on top of it. It would be awesome if you could add an input in the settings to move the spinning wheel to the left or right. I also change the way the spinner "looks". Being able to modify this from the settings would be useful as well.
Great product, though!
