Onion Skin Colour Settings

Hi all. 

I just started using the version 2.0.2 of animate and got really annoyed with the default blue and green onion skin colours. I also noticed the option to change those colours has dissapeared, so i'm stuck with these awful blaring blobs of blue and green while I work. I cant see anything with how bright the contrast of the before and after frames are, making it impossible to use. If someone from Adobe reads this, please re add the option to change the colours, and if possible, add an option to not have colours at all and go back to the slightly transparent option that we had in Flash. 

Thank you for your time.
