System Tweaks

Codes and passwords should not sit on your clipboard for hours. A timed, pattern-based wipe with a cancel window — plus the manual tile you will actually use most.

Fit more content in one app and larger targets in another — density swapped on launch, restored on close, with your stock value recorded before anything changes.

Every command in this category, organised by job: grants, settings keys, power, roles, locales and verification reads — each listed with its undo and its read-back.

Whitelists, AppOps and standby buckets are fully scriptable; MIUI Autostart and Samsung’s sleeping lists are not. The layered map of what shell can and cannot settle.

Stop re-training adaptive brightness daily. Time-based tiers, the adaptive offset key for a gentler bias, and the hand-back rule that keeps the sensor in charge.

Big-button car launcher when the car Bluetooth connects, your real launcher back when it disconnects — built on the HOME role, with an anti-bounce delay and full undo.

Cable in, tethering on — the always-works one-tap assist, the Helper and shell routes with their limits stated, and the safety constraints auto-tethering demands.

No universal split-screen API exists, so the honest routes are three: OEM app pairs, guided UI sequences, and sequential launches. Which to use on which brand.

Separate the apps that may buzz from the apps that may not: notification channels first, system states second, MacroDroid custom patterns for the people who matter.

Per-app languages are real on Android 13+; whole-system language switching by macro is not. The honest map, the ADB locale commands, and the stacks multilingual users actually keep.
