First, let me congratulate you on a great and exciting product.
My image folders contain a modestly large number of raw files which exist on external USB 3 drives. When Affinity Photo's Media Browser is selected it attempts to display thumbnails of each raw file. It is taking about 1/3 to 1/2 second to display each thumbnail which of course will take forever to display the contents of my folders which contain anywhere from 3,000 upwards of 6,000 images. If I just leave it run, it will stop displaying thumbnails after a few dozen are processed resulting in the browser hanging. I can exit the browser but it does not act correctly after hanging. All my images are Canon raw files either CRW or CR2 format. If Affinity Photo is creating a high quality thumbnail as a reference to an image, I would expect the ability to cache the result so that it not be regenerated each time the image is accessed. Also having a number of other image products such as Canon's DPP and others who's browsers generate thumbnails without caching they only take only a few seconds to display the entire folder of 6000 images. So there is a problem. If the extra time is due to the generation of high quality thumbnails, I would expect that to be a user selectable choice and that the generated data be cached in a user selected folder.
Best Regards,
Bob
