Option to make "beta" mode default when opening a stream

[MariusAlbrecht]

Is your feature request related to a problem? Please describe. I personally like the beta mode more than the actual live mode and always have to switch into it normally

Describe the solution you'd like A toggle in the settings to make the beta mode the default when opening a stream (potentially with a warning or smth if the beta mode is actually less stable)

Describe alternatives you've considered n/a

Additional context n/a
