Interface decisions, written down: who had the problem, what I tried, and why the one that shipped won. Every demo is live.
Tokens arrive in bursts. Painting each burst the moment it lands reads as a stall, then a lurch. I'd rather the reveal keep a steady rhythm.
Bold makes text wider, and a toolbar centred on the selection slides with it. The obvious fix made it worse. The right one came from asking what never moves.
Typing, pasting, an AI rewrite and a collaborator all change the document through the same door. Here is why I think that's the only honest design, and what it costs.
