What bugs me a bit about the Affinity products is that basic functionality is missing, and users have been requesting these things to be fixed for years now. For example, TGA and WebP export are missing, no arrows for vector lines, the custom bevel layer effect looks terrible (obvious banding), no vector fill patterns, layer thumbnails cannot be scaled, no option to use ctrl/alt-clicking layers to create selections, curves lack controls, nested filter layer masks cannot be selected in the layer stack, ... It's quite a list.
I do understand these are young applications, but they keep adding larger new features without improving the core functionality.
Well, no app is perfect.
