Figma's nested folders story is the most honest thing about design tooling you will read this week. The rest of the feed is about judgment, ethics, and the quiet cost of AI orchestration.

Wireframes are back. Not as a nostalgic throwback, but as a serious argument about what the endgame of product design tools actually looks like. A sharp, contrarian read that questions whether we have been building the wrong thing this whole time.

Code, craft, and the making of nested folders

Figma’s own team breaks down how they shipped nested folders. The interesting part is not the feature. It is the workflow: treating code as a proposal, turning handoffs into conversations, and building a new way of working to get there. A rare behind-the-curtain look at how a design tool company designs its own process.

Defining ethical design for machines

The conversation about AI ethics usually stops at “don’t be evil.” This piece pushes further: what does ethical design mean when the user is a machine? A useful framework for anyone building interfaces that agents will interact with, whether you planned for it or not.

The most valuable thing a senior designer owns is taste. This piece argues you should be systematizing that taste into reusable principles, not hoarding it. A practical take on codifying judgment so your team does not have to rediscover it every time you are out of the room.

Zach Holman traces three of the biggest inflection points in his career back to cold outreach. A reminder that the most underrated design tool is still a well-written, specific, and slightly brave email. Short, honest, and worth sending to your team before they draft their next one.
