StarTube is the official successor to CustomTube, allowing you to use the 2011-2022 YouTube layouts. It is highly customizable, and can be used for many things, ranging from just enhancing the default V3 experience, to using an entirely different layout.
Settings are accessed the same way V3's settings are, the bottom right corner of the screen.

Make sure to disable the regular version of StarTube before using this one (and vice versa).

Current version is 2.2.0 Beta 1.
