The settings Android keeps to itself.
A status bar clock you compose from pieces — mix time, fuzzy time, date, day and battery, then set size, colour, weight and font, with a live preview. Per-app display density, font scale and refresh rate, with presets scaled to your own device. Notification rules that block a message before it's posted, by app or keyword — which no notification listener can do, since by the time one sees a notification it has already arrived. Hardware key actions, a read-only power inspector, and a boot guard that disables a feature and reports itself if the device ever fails to boot with it active.
Alpha. Verified on one phone so far — a Nothing AIN065, Android 16, Vector 2.2. Three of eight features are proven end to end there. The rest install correctly but haven't been observed doing their job yet, and the app names which is which on each feature's own card rather than claiming otherwise.
