Option for Smaller Material Thumbnail?

Can we have a 4th option on the Material thumbnail to make it much smaller? Like bring it from 150pixels tall to 40-ish?
If I need to see a super-detailed version of a photographic material, I’ll just open the image file, or apply it to a face in a model, or render it.
I mostly work in solid colors, and the thumbnail taking up so much available height on my tray is forcing me to scroll and collapse other trays way more than I’d like to for daily functions.

The trays have gradually taken over real estate, so if there’s anything to cut this loss, I am all for it.

You can separate the trays with pages so no need to scroll to another category
