It's also very easy to use and feature-packed, take a look!
There's a plethora of builtin spinner styles to choose from!
And you can easily create your own, there's builtin support for several special effects like frames, scrolling, bouncing, delayed and compound spinners! Get creative!
Also bar styles!
To install, just:

That's it, you're good to go!
