Hello Kalman,
Thanks for trying WP Socializer. WP Socializer is extremely customizable, so that you can use it for any theme or design.
For the 1st question, I need your site URL so that I can work on the sliding share bar to get like what you want. When you mention the URL, Ill suggest you the necessary changes which you have to make.
Also note that, templates are free and you don’t need to buy for any cost. Ill do the necessary customization free for you.
For the 2nd question, just go to Placement -> Template 1/2 -> Uncheck “Show in Excerpt”
Hope this works.
Thank you.
