P: take a block of images and move it into a new row

I really love Lightroom Classic for so many of its strengths. It already has superior image organization to many applications with starring, keywording, and color labeling. But there is something missing -- a way to separate photos into groups in the library module.

Put simply, I want to be able to take a block of images and move it into a new row, like separating one paragraph into two. This could be as simple as adding a spacer button which, after the selected photo, moves all subsequent ones into the next row with a space between. Or it could be sophisticated, so that you can label entire groups with large headers, or create different configurations by dragging groups above, below, and next to each other. Maybe there could be multiple layers allowed too.

If something like this were to be added, my workflow would be immensely expedited as I often have trouble managing photos in a collection when I want them all in front of me, but in distinct subcategories. I especially disdain scenarios when I have to create sub-collections in a collection set all for one shoot. Stars and colors are not what I'd be looking for, as they don't provide enough visual separation and they are used for other aspects of image processing, such as whether to keep or toss a photo -- not to mention there are only five options.

If there is something I've missed, let me know. I made a rendering of what it could look like.
