• Your best users are the ones who complain. A user told me at 10pm that my uninstaller just nuked his shell config. My instinct was to get defensive. Instead I traced it — and found it was worse than reported. That one message led to rewriting the entire uninstall logic from scratch. Every angry bug report is a gift.
• Your favorite metric can lie to you. I built a cache that reduced file reads from 2,000 tokens to 13. Great numbers. Then a user told me: "Models waste more tokens working around stale cache than the cache saves." He was right. The fix wasn't removing caching — it was making invalidation smarter. Your dashboard can look great while the experience is terrible.
• Saying no is the hardest part. A new feature would have let me compress all tool output automatically. Massive savings on paper. I designed it, prototyped it, then killed it. Because when compression eats an error message, there's no undo. Protecting quality beats shipping features.
• Community is a relationship, not a channel. When someone reports a bug, my first response matters more than the fix. "Will check" buys time but shows I'm listening. Following up shows respect. Shipping the fix shows they matter. My best testers are people who once filed angry reports.
• Ship the boring stuff first. Nobody cares about your adaptive entropy-based compression algorithm if the installer breaks their dotfiles. Get the fundamentals right — install, uninstall, doctor, setup — before you get clever.
• Focus means killing good ideas. My backlog has 50+ ideas. Each one is good. But spreading across all of them means none become great. Rust helps here — the compiler forces you to finish what you start.

The native applications lost the battle.
Windows is not able to offer a consistent native UI over a decade.

The UI inconsistency in Linux was created by design.

MacOS is no longer the safe heaven where designers can work peacefully.

Electron Apps have , but they also lack off visual consistency and keyboard-driven workflows.

Some restartet from scratch with Dart and Flutter UI to replace Android legacy things. Google gave up because they needed a monopoly or a large enough market to succeed.

Zed did the same thing in Rust: they designed their own cross-platform GPU-renderer library. It lacks integration with the host OS on itself though.

On the contrary, TUIs are fast, easy to automate and work reasonably well in different operating systems.
