ADOBE PREMIERE, ONE OF THE IPHONE'S BEST VIDEO-EDITING APPS, IS NOW ON ANDROID

Adobe is bringing its redesigned Premiere video-editing app to Android, nearly a year after its iPhone debut, replacing Premiere Rush, which loses support September 30. Layouts adapt across devices, pairing footage and a multitrack timeline side by side on foldables while still running on candy-bar phones like the Pixel. The app is free with no login required, though Firefly-powered features like Generative Fill require paid generative credits once the monthly allotment runs out.

UX-CONTEXT DESIGN: USING UX KNOWLEDGE TO INFORM AI-GENERATED DESIGN

As more interface work turns AI-generated, research and design output shifts from human-facing deliverables toward curated context that guides AI, dubbed UX-context design. DESIGN.md, which Google Labs open-sourced in April 2026 from its Stitch tool, encodes a product's visual identity for AI tools in exact values and plain-language guidance. A hypothetical broader file, UX.md, would add research findings, interaction standards, a glossary, and user and world models as a continuously updated source.

MODERNIZING A LEGACY SYSTEM? YOUR BEFORE/AFTER ISN'T THE CASE STUDY

Strong modernization case studies focus less on before-and-after visuals and more on the design decisions behind them, highlighting the judgment calls that shaped the final product rather than the process or visual refresh alone. Employers want to understand what changed because of the designer's thinking, not just that an outdated interface now looks modern.

NOTHING HAS CHANGED OTHER THAN HOW WE TALK ABOUT IT

Agentic AI can dramatically speed up the research and problem-definition phases of Design Thinking by analyzing assumptions, synthesizing evidence, and pressure-testing ideas, but human judgment remains essential for validating outputs and making design decisions. Rather than replacing designers, AI shifts their role from generating information to evaluating evidence, challenging assumptions, and deciding what should be built.

DESIGN SYSTEMS ARE A COLLECTION OF DECISIONS

Design systems amount to collections of already-made decisions, so mechanical checks can prove straight from the artifact whether an AI agent used real components and correct tokens. Judgment-based evals still have an answer key when the system has documented a decision, like a required confirmation pattern for destructive actions. Visual evals work against a known reference, but deciding whether a new visual direction deserves to exist should stay with people.

SPATIAL UI DESIGN: TIPS AND BEST PRACTICES

Augmented reality design differs from screen-based UX, demanding attention to physical space, bodily comfort, and the cognitive load added to real-world distractions. UX consultant Frank Spillers' guidelines favor real-world physics, direct hand gestures over menus, context-aware triggers, and short, interruptible interactions. Content should stay within about 30 degrees of a user's central field of view, never past 50, and sit between 1.25 and 5 meters away.
