The UI design of Adobe Express today violates the platform guidelines the application runs on AS WELL AS Adobe's own styleguide. The current appearance AND architecture design choices, acquired from the original design created by the original developer from which Asobe purchased AEx, was not repaired and refurbished to fit Adobe's own styleguide let alone the platforms the app runs on. Please review Apple, Google, and Adobe's own guidance on GRAPHIC DESIGN and USER EXPERIENCE DESIGN. As a result of the ongoing failure to adapt the original design properly, usability is compromised. Example, there is so much stuff jammed into top level displays, finding affordances let alone general wayfinding takes longer than it needs to take. Color palette is undiscernible and unlimited making for a look and feel that is different than all of Adobe's other apps damaging Adobe's branding.
In short, this app UI is a mess, looks like developers simply kept adding features ignoring progressive disclosure principles, composition principles, established IA (information architecture) standards, and a host of other UI bugs and deformities making for the entire app less usable let alone less attractive to potential customers.
UX design is not an add on (also elaborated on in Adobe's own guidelines) and graphic design is not decoration and surface polishing of glorified coders; it is what makes AND BREAKS a product. Fix this stuff.
