The "About Media Viewer" link wastes an entire horizontal row of screen space, and often the caption is cut off in an ugly way. Sometimes it's not obvious that the caption continues below the scroll box when there are line breaks exactly where the caption is cut off, because the scroll bars on the caption are invisible.
The scroll bars should never be invisible if the caption won't fit, or alternatively the bottom of the caption could fade out with alpha transparency so it doesn't look bad on dark mode, and/or have a down arrow / chevron icon so that you know there is more content available below.
By moving the about link to the right corner, it will expand the vertical area available for the image caption, which is what 99.99% of the users actually care about.
