I installed Social Media Feather on my website and it loads quick and works brilliant except I found a couple of problems.
Initially I loaded it using a short code and found icons disappeared when I set them to be share only. I then used the automatic loading after posts, which worked great.
However, later I was editing some posts and found certain features stopped working. I couldn't set hyperlinks or go into the text mode of the editor. After restarting the browser the problem persisted so I deactivated this plug-in and all the editing features started working again.
I've had to disable the plugin to edit posts.
