Bridge Folder thumbnail icons far too small

Good day

here is something that has annoyed me for many years.

Why are the folder thumbnails/icons so very small?

I have my own folder icons and most of them are difficult to recognize when small!

I can't think of any reason why this can't be resolved! Increasing the thumbnail grid size does not change the icon size! Surely this is an issue that can be quickly and easily be changed?

I'd really appreciate that

Thank you
