Hello I think that everyone has seen that the external subitles height on the screen is not adjustable! Is there any possibility that WD will add that feature?
Your post sounds more like an Idea or a Feature Request. The best place for this is in our Ideas Lab. This way someone from WD will be sure to see it. However, I would search first and make sure that there isn’t another idea similar to yours that you could add your post to and vote on.
