Hi Ajinkya,
Thank you for using Mighty Pros & Cons.
It’s not possible at the moment as the plugin is not created in PHP but in ReactJS.
It’s a build file so you’ve to create a webpack environment to update the code.
Though, I totally agree with you on the heavy FontAwesome calls.
Let me fix this on our end and release an update for you.
I’ll let you know here once it’s done.
Thanks.
