Does not work, dev will not fix

I installed this plugin last spring. I selected all Visible Buttons, except StumbleUpon, but starting May 2014 it started showing only 3 things:
1. Facebook Share
2. LinkedIn
3. Print, PDF, Email

What was missing:
1. Facebook Like
2. Google +1
3. Google +1 Share
4. Twitter
5. Pin It

All 8 buttons I would like to have show up in the Preview on the settings page in the Admin UI, but only 3 buttons show up at the bottom of the content area, where I placed shortcode.

I found an existing thread where others were having this same problem. We all addressed our problem and asked for it to be fixed, and the dev’s solution was to go back several versions to 1.2.8 (as of this review, the current V is 1.2.14). That’s fine for a temporary workaround. But here it is 3 months later, and there have been updates, but there has been no other responses to the help ticket nor has the problem been addressed or fixed on any of the updates.

Deleting this plugin and going with something that works, and that the developers care about whether it works. I understand that this is free and probably a side project, but there is a minimum amount of responsibility the dev takes on to put out a working, functional product on WP, even if it’s free.
