This app adds a feature to Options, "Backlight Timeout Warning", that warns you with an adjustable very-brief vibration shortly before the backlight is about to fade or turn off, so you can move the trackball or wheel, brush the trackpad, or touch the touchscreen to keep the light on before it turns off or starts to fade.
** For this feature, there is no icon, just added settings in Options.
There is no impact on the phone's responsiveness and no significant impact on memory.
