Regular users will see same options as in v1.0 but you can enable (if you want) Advanced mode to bring some options, such as:
• More options for Navigation bar
• Player options
• Overlay options
• Shorts options
• More options for Tab bar
• Startup page selection
• Option to restore default settings
• Sideloading support - activates only if app was sideloaded
Tweak preferences can be reached from YouTube Settings (YTLite cell)
Advanced mode can be activated inside 'Version' cell - yes, its tappable. Then simply reopen YTLite settings
