One at least has a WEBP preview in the "Save as" dialog (if you click "Options…"):
Though ofc it would be better suited to have WEBP support in the "Save for Web" dialog with features optimized for the use case such as:
- Larger preview
- Adjustments
- Web compliant file names
- Infos like file size, time to download
All great for the use case of web exports
How are the chances for implementation?
