One of the great things about Photoshop is its actions. There is a big market in this that is a real challenge for Affinity to crack. Other programs, such as On1 Photo Raw, have very easy to use presets.
Affinity seems in its early days with basic macros and single-adjustment presets. However this also means that there is opportunity to overtake Adobe with a more sophisticated 'recipe' system. Things to include:
Scalable images of recipes as applied.
Nested system so you are not faced with all recipes at once yet can have many on tap without overwhelm as you search for the one you want.
Use of tags so you can search as well as browse for recipes.
The ability to edit recipes, possibly in a text format.
Ability to post a pop-up box at any time, including for choices, sliders and simple text messages.
It's possible that a new format is needed for this, beyond presets and macros.
[historical note: back in the 80s I implemented a macro system on an HP wordprocessor. Customers loved it. It was also really helpful as an automatic test system!]
