Increase image/file preview size for asset gallery block

Hi there,

It would be very good if you could tweak the image/file preview size for asset gallery blocks like you can on the media tab with the slider for size.
We figured while working with a client that the preview size of the images is sometimes very small to be able to distinct similar image quickly and forces us to wither zoom in on the page, or have to quickly an image to check what image it is, which can be time consuming while trying to reorder images.

Thanks for all the help!

I absolutely second this! We use Datocms for a travel website and need to curate images for hotel and villa properties. The size of the images in the gallery blocks are too small for editorial review, and we need to open images individually to check them fully.
