Bigger Thumbnails in Summary View (for folder view, youtube content)

Can we have larger Thumbnails (heck full size?) options for viewing in FOLDER mode, in a library, while in SUMMARY view? This way those of us that add youtube content to a custom library, can see the entire thumbnail. it is a grabbed youtube 720p image it won’t be huge (manually added via POSTER in edit section)

This can be done via a tick in a library’s settings, or maybe a drag-able bar for the thumbnail line. (between “folders + gopher” as example) Though that seems less uniform.

(better example of cropped image)
