what you are describing sounds like a template variable (tv).
create a tv with a rich text input, and apply it to the templates which you wish to have the additional input, and you’ll be good to go! once you start playing with tv’s you’ll see they provide many different options and possibilities, not just an additional text area.
considering that i just started, I still don’t get whole TV potential..
could anyone explain that little bit more plainer?
thanks
Radio sucks!
