I built nomousemode to solve a specific problem. Every day I was losing focus switching between windows. Mission Control is slow, clicking the dock breaks flow, keyboard shortcuts aren't discoverable across different apps. The solution is simple: a keyboard-driven window switcher where you define memorable shortcuts for your windows. Hit your custom shortcut and jump directly to what you need. No mousing, no menus, just instant context switching. I've been using it for about 6 months and it genuinely changed how I work. Fewer interruptions, less RSI from mousing around, stay in flow state longer. The app is lightweight, works with any macOS app, setup takes maybe 5 minutes. No complex configuration needed.
