I always do this. I don't have a problem with the edit function, as I occasionally use it. I do however worry I'll accidentally clear the entire conversation. Why is that even an option, much less such an easily accessible one? It is somewhat redundant and unnecessary when you could just swipe-delete the conversation from the list. This removes the whole conversation from the list, whereas "clear conversation" leaves an empty window. I can't imagine when you would want to wipe it clear and leave a blank box. Anybody?
