Yes, yet another battery shortcut. Rather than have 30 battery shortcuts, the goal here is to make one with a menu to select an option:

•Normal •Normal (Wifi Only) •Low with Wifi •Low with Cellular •Ultra Low •Charging •Charging with DND

Now intelligently saves last brightness level. It does not save it when switching to normal modes, and uses a default normal brightness (75%) if the saved level is less that 50% when switching to normal modes.

Should be easy enough to customize. Displays the current battery level and brightness in the menu title, and makes a recommendation.

Credit goes to just about everyone who's made a battery shortcut so far. (Thanks!)
