Contributor Dictionary Bug

On the Contributor site, the word "shifter" is missing from the dictionary. An exceedingly common movie goof is a revealing mistake, a scene depicting someone driving, but the shifter is in the Park position. I've submitted several of these, and every time, I get a spelling warning over the word "shifter". It's a common English word, representing what is present in literally billions of motor and non-motor vehicles world-wide. I have to over-ride the spelling "error" (which, of course, is NOT an error) every time. This word should be added to the Contributor dictionary.

In anticipation of any question about why this is being submitted here, the "Send Feedback" link on the Contributor site leads here.
