Kmail/Kontact question

[charlie]

Hey all. In Kmail/Kontact, in the email viewing section of the program, 
there's a black bar that says "HTML Message." I used to be able to turn that 
off but now I can't seem to find the option to do so anywhere in this new 
version of Kubuntu. (19.04). Will this option return later on in a future 
update to the software? Almost all emails are composed as HTML these days and 
I'm ok with that because it's cool to have pics, links and all of that. I just 
don't the bar on the side.
