I am curious if there is a way to remove the red text that gets put into mathmode when you use a package not standard in lyx. For example, when I wish to use a dsfont character and the improved right/left parens of mleftright, in the lyx window I see

even though the output compiles properly as

Does anyone know a way to alter this? I would prefer that Lyx actually puts large left and right parenthesis and dsboldface letters directly into my lyx window, but if there is a way to simply stop the redtext from appearing I would be happy to get rid of it. Thank you.
