Great functionality, but layout problem and no support at all

First the positive, for which I had originally awarded 5 stars:

Clean buttons, localized, both share *and* like buttons for FB, and most important: They automatically display not only on posts and normal pages, but also on WooCommerce product pages (if you choose so). I found no other plugin so far that does this.

The negative:

– The buttons take some seconds to load, probably because they are loaded from an external server. That’s not such a big problem, BUT:

– Support for this plugin is virtually non-existent, the author seems to reply to posts only on a random basis every few months.

– The buttons break the layout of my theme (VendiPro) by causing a gap between the main page and the footer. No chance to repair that due to non-existent support (see above).

This causes me to go down to 2 stars and to keep looking for an alternative.
