Tried this on a super-simple build-it-in-a-day site and it worked well. Not sure how it would do in a more complex, customized site. It was honestly the only free plugin I could find that included the thumbnails on the slideshow without a bunch of coding I don't have time for on this project.
I emailed support to ask for the responsive update, and they sent it within minutes and it worked great. Only needed to add a small overflow: hidden; styling to the CSS because the thumbnails were overflowing their slider box.
Slideshow is currently 100% of the width of my content on my theme, so I'm going to change that and it's not an option in the configurations page, but considering the responsive update isn't even 100% out of beta yet, I think that's fine.
Thank you for this plugin!
