Good feature about font style and font size, but not great.
And I don’t wanna request about more UI improvement features which I can do it myself.
Unless I can’t do it myself.
Of course, If Coda will improvement, we (all codaers) appreciate it. Such as Google font ,
Serif is really quite normal 
For example:
Design backquote style
font, size, background color , etc
I’m using Noto font from Google font.
