Super light plugin – it isn't slowing site at all – attractive look

Interesting and promising new plugin concept for social networks. Part that attracted my attention was the following sentence that Plugin’s Author wrote:
“Coded with best practice, it is super light and will not slow down your site.”
I was a bit sceptical at the first, but this is, indeed, true as I noticed that the plugin has only 44 kb and it is super fast without queries towards social networks. It isn’t slowing my test site in any way so I will give him a try on one of my productions sites as soon as Author add an option for sharing pages as well, not only posts (which is planned to be added in one of the following releases).
I installed it on test site and played a bit – it is very easy for setup with enough options you can turn on/off nad Author is promptly solving all reported bugs/issues… and plugins is fully functional in his free version.
Could it be better?
