I appreciate that you've taken the time to give me this information. However, with all due respect, I know and have used these methods. I can get Nik and a few Topaz filters into the Affinity filters menu, but that's all. I can't get all the Topaz filters, or Luminar 3 or On1 RAW 2019. To interact with these programs I have to create a special folder in my Photographs folder just for images developed by Affinity, open those images in either On1, Luminar or Topaz for special processing, save and return them to the folder and then open them up again in Affinity. That's a real headache. I don't have to do that with Photoshop. All images open in Bridge for viewing, and all of the above-mentioned programs work perfectly in the plugins folder in Photoshop. As I've said, it's easy for me do enhancements in these programs and then return to Photoshop quickly and smoothly.
Again, I will ask the same question. Does Affinity have any plans in the future to create a Bridge-like browser, being able to view all photos, and are there any plans that will allow Affinity to shake hands with other photo development programs, as Photoshop does?
