At this point we honestly need a unified cross-platform visual IDE for web & mobile design that can export as native, PWAs, responsive websites/applications, and is future-oriented for AR/VR experiences.
The fact that we're in 2022 and the industry doesn't have tooling for teams to make this happen quickly and efficiently is a little underwhelming, and has mostly to do with artificial des/dev walls created by companies to protect their platform-specific advantages (understandable, but not good for innovation).
With the absolute plethora of quality UI kits and design systems available, a generally accepted Right Way(tm) to do things based on design patterns, and the ever-pervasive presence of Jackob's Law in UI/UX, there is no reason why tooling shouldn't exist to create an application with standard processes and procedures in an ultra-efficient fashion.
Design teams should be able to collaborate with devs in real-time, dragging and dropping coded elements into frames that can be customized visually, fed into a design system, and handed off to development in a one-to-one fashion.
No guesswork, just clean UI's and clean code.
We are quickly moving towards an era of tokenized design, and this would be the next logical step.
