A control that emulates a split-flap display. It steps through a fixed array of characters (predefined by the user) until it reaches the target character. Each character gets vertically split into two halves, and when the current character changes, the upper half will drop down.
The demo shown in the GIF above is included in this repo here.
Once the plugin has been enabled in the Project Settings, its documentation can be accessed directly from Godot: press F1, then search for "SplitFlap".
