Hello Ioanmorris,
First of all sorry for the late reply !
We are really glad that you’re enjoying the plugin, about your question, as you noticed, there is not a lot of customization possible through the dashboard, we were planing to add more options in the futur, but it wasn’t a priority.
So basically, you’ll have to do it manually, by coding it yourself, you will find the icon css in the plugin directory/css/asi.css ( note that if you want, there is a LESS file too ).
From there you should be able to easily increase the size of the icon by modifying the 3 lines :
font-size: 30px;
line-height: 30px;
width: 30px;
The problem is that for centering, I used Javascript to add css depending on the setting in the dashboard, so it will override the position set in the css. And to be honest, it’s a bit complicated I think if you’re not used to Javascript ? If you want to try the file is js/asi.js, there is a function called placeIcons() that you could try to edit.
However, I will try to add a “center” setting myself as soon as possible, and a better icon customization from the dashboard.
So for now, my advice would be to try to make the icon bigger through the CSS, which should be easy, and wait for an update from us for a centered icon. I can’t really tell right now when an update will be available since we are both pretty busy right now with other plugins and work, but I think it could be live within one month or two ?
Sorry for not being able to help more than that,
Best regards,
