One thing that helps Krita is it has focus on who they are helping (people
that can draw and paint). Photoshop caters to a lot of different industries
- which is why it has 1,000 features built into it (which is both good and
bad). When you get feedback from people, they oftentimes don't tell you
important information about who they are. Are they graphic designers, web
designers, photographers, 3d texture artists, animators, or maybe beginners
just trying to get into basic image editing like cropping. You need to find
out who you are trying to help. Graphic designers don't normally do
painting and illustrations, and web designers don't usually do animation.
This is why pretty much everyone only uses 2-3% of all the features in
Photoshop. The rest of the features are just useless to them and are UI
Trying to do a 1:1 copy of Photoshop isn't a good direction. That program
has had 30 years to add a giant amount of features that have turned it into
the powerful/bloated software that it has become. As a UI/UX person, I
would focus on finding the people you want to help, learn about them, and
give them a product that they are excited about.
