Hi there,
#1,2. I fixed this issue
#3. I added css custom into file style.css ( child-theme), to custom color, you need to edit this color:
.site-header-account{
background: #your-color !important;
}
.site-header-wishlist{
background: #your-color !important;
}
.site-header-cart .cart-contents:before{
background: #your-color !important;
}
#4. Custom Icon: We just support icon from list: https://demo2.pavothemes.com/poco/icons/, you need to select icon then use css custom to edit this icon.
#5. I checked and it’s still works normally.
#6. I fixed this issue.
