The idea is to leave Multicam Legacy mode as it is and create this new option. So the user can choose to work in the conventional way or in this new way.
This layout change would be very useful mainly for users who only have one monitor.
It would allow you to see the cuts, crossfades and FX effects applied to the events in real time in the Main Preview.
It would no longer be necessary to switch between Enable Multicam Editing and Desable Multicam Editing (Ctrl + Shift + D) as it is traditionally done.
