I want to request the support for the DNG/RAW file format. It should work but it is not working for me. I’ve tested a picture with the Photopea image editor (https://www.photopea.com and GitHub - photopea/UTIF.js: Fast and advanced TIFF decoder) as it is mentioned if it works here it should work with Tagspaces, too - and it is working with Photopea without a problem. Tagspaces Pro is not showing a thumbnail. preview or the picture.
