I can adjust the style of these Captions, e.g. Background Color, Font-Style etc.
I would like to have a semi-transparent Background-Box that is also blurred a bit for all my Captions though. I can create a semi-transparent blurred Shadow for the Text itself, but that's not quite the same, because the shadow still creates a shape similar to the text. I would just need an Option to Blur the Background-Box.
