First of all, thanks for this awesome plugin. It's absolutely fantastic. Easy to use, lightweight and generally just kickass.
There are a couple of cool improvements that would be great - although I'm aware that you're trying to keep this as simple as possible.
1) A text option would be nice, with the title on a transparent background at the bottom. I know it can be customized to do this, but a native option would have been nice.
2) The pagination is left aligned and it would have been nice if it was centered by default. Once again I haven't tried yet, but I bet there is a way to fix this via customization. :)
3) Potentially messier and it might defy the purpose of this lightweight slider, but a thumbnail image of the slides would have been great. With a bit of hacking I'm sure this can also be customized though!
Thanks again for the great plugin bud.
P.S. When you're not making great WP plugins, you should consider a career as a Penn Jillette double. I love that guy!
