i like to see previews supported for png files. This is a common file type and should be supported Especially since it is one of the options supported for export to creative cloud from photoshop touch. It would make a lot more sense.
You would want to go here for feature requests: Photoshop Family Customer Community
Photoshop does support PNG files.
Are you using a different product, and did you post in the wrong forum by mistake?
