Subcategory icons on categories route
Regarding subcategory icons being shown on the main page in 1.01, I noticed an issue when a category icon is used w/o a font awesome icon.
- Custom category icons aren't shown on the main page for subcategories
- If a font awesome icon is also used, it is shown instead.
Request use of a scaled down subcategory icon, or the ability to use icon + font awesome, but not have font awesome shownn on the main page.
