Finally a plugin that has lazy loading and does not bog down pageloads. First of well done...
Ok i have some suggestions that i think will really make this plugin fantastic.
1. Ability to set either an align Left or Right for the buttons in settings
2. Easier control of controlling margins for the buttons via the settings page if possible without the need to edit css file direct, i find that the default settings spacing between buttons is too much
3. Ability to use custom icons instead of the default one easily from backend.
4. Add the shortcode instructions to the settings page, i did not know it existed until i went to the FAQ page.
Thats it, well done i love this plugin.
