For those of you puzzled as to how three separate apps (Photo, Designer and Publsher) have become one (Studio), as a long-time user it was always clear that under the hood this was always the case. Indeed such interoperability has clearly been built into the Affinity suite from the ground up.
This is 100 miles away from the interoperability of Adobe's Dynamic Link whereby apps such as Premier and After Effects are 'united' in a manner that feels clunky and forced. Almost all Adobe apps were acquisitions, and most of them are now horrendously long in the tooth. Uniting them seamlessly would be impossible.
I adore Affinity photo for its top to bottom support for high dynamic range images. Editing RAW images is a buttery smooth dream, compared to Photoshop, which feels like I am banging my head against the software.
