I'm not totally sure if this is intended behavior, but the wrapwidth sign and numbers get wonky with concealed characters (see first image; compare second image where concealed characters are revealed). In my opinion, the sign should work this way --- regardless of whether or not characters are concealed, that is where the line is getting wrapped. However, the numbers are frankly unusable, they really should be in a line. As a side note, it would be nice to have the option of putting the wrap numbers on the left next to the line numbers so they can be a little more physically close to their lines.
Also, THANK YOU FOR MAKING THIS!!! Editing large blocks of text in wide windows was getting annoying.
