I didn't have to tweak anything in this plugin to make it work with my custom WordPress template. Just move the floating display a few pixels left through the settings panel and ready to go. Lazyloading buttons is a nice feature, I use Google's Mod Page Speed for server caching, WP-Cache for site caching and activated lazyload options in digg-digg, as a result my site loads pretty fast and doesn't break anything. For those who want to see it working before downloading, check it on my website: [ link redacted, please do not post links in the reviews section ] Widget for Bootstrap Hero units.
Keep up with the good work guys!
