HTML features for description field

Hi,

I build a site for an artis (paintings)
For her it is important to add thingss linek "sold" and "Reserved" to het paintings.
In this world a red or a green dot is common.
Now I made some CSS rules to make it happen:

/*----VERKOCHT----------*/
.rsmg-item-body .rsmg-item-description span:after{
font-family:"Font Awesome 5 Free";
content:"\f111";
color:#ff2200 !important;
}
/*------OPTIE------*/
.rsmg-item-body .rsmg-item-description strong:after{
font-family: "Font Awesome 5 Free";
content: "\f111";
color: #33CC00 !important;
font-variant: normal;
text-transform: none;
}

But it would be very nice to make the description field a html editor instead of the field it is now ;-)

Regards, Theo
