I look around the site you shared. But I cannot find what you are talking about.
Could you please send me some screenshots?
Can you please look at another demo site please: http://onlinedemo.sitemile.com/?theme=pricerr
You will see that at top they are showing categories with images like: Accounting, Digital Products, Events etc.
DE currently shows icons along with Category name, and FontAwesome still don’t have a massive list of icons that each and every word can be expressed using it, and in this scenario according to me category images can help.
Please have a thought about my suggestion.
