Saw the new inbox briefly and had a thing to put out there with others. Is it possible to bring the current 'selected items are also highlighted in a different color' that we have at this time? The checkbox alone is often not enough for me when I am going through to select things to delete or mark as read, and the visual cue of color distinction goes a long way to me not accidentally deleting something I didn't mean to or figuring out what I missed.

I hadn't seen that mentioned yet (as of when I started typing this comment at least) and I expect that there will be others like me who find that current tool helpful to retain if it wasn't already on the books to keep.
