Today, the asset thumbnails shown in list and grid views are generated using a Cloudinary transformation that scales images to a maximum width and height, and then automatically 'pads' any extra space using the predominant color from the image. (c_lpad,b_auto).
This feature would enable account admins to set a customized transformation to generate the thumbnails in your account. For example, you could:
Set a solid padding color, such as gray or white, instead of predominant color padding.
Apply a different crop mode. For example, c_fill,g_auto
Define a conditional transformation. For example, you could set a transformation that adds an overlay icon to the thumbnails for assets that have a specified tag. e.g. Show a 'Sale' label on assets with the tag, "sale".
How valuable would this feature be for you? If it existed, which transformations would you want to apply?
