Essential Key Tools v1.0

First release of Essential Key Tools — remap the Nothing Phone Essential Key to your own actions, no root required.

Highlights

• Four gestures, four actions — single / double / triple / long press, each mapped independently (launch app, flashlight, screenshot, lock screen, media play/pause, ringer cycle).
• Runtime scanCode learning and in-app accessibility-service enablement (one-tap via Shizuku, or a settings deep link).
• Single-press unlock wizard — Shizuku, manual, or ADB paths, with one-tap restore and live per-package status.
• Home screen shows live service/unlock status, a contributor list fetched from GitHub, and a shortcut to the system per-app language screen (English / 繁體中文).
