Top location

Not via the UI, but with CSS yes, anything is possible 🙂 The css that controls the position of the button container looks like this:

#ssb-container {
    position: fixed;
    top: 30%;
}

So say you wanted the buttons to sit higher (nearer the top) you might adjust 30% to be less like this:

#ssb-container {
    top: 15% !important;
}

The important! attribute overrides the value coming from the plugin. So you can add ^this code to your theme and it will override the css that’s in the plugin.

Hope that helps point you in the right direction to achieve whatever you want.
