System Information
Operating system: Arch Linux
Graphics card: GeForce GTX 1060 6G

Blender Version
Broken: Blender 2.93.1
Worked: n/a (never used blender before)

Short description of error
I am following the manual for MultiCam setup https://docs.blender.org/manual/en/2.93/video_editing/sequencer/strips/effects/multicam.html

However even after searching for 3 hours now, No selector in the "Preview" windows can be found to select the channel being displayed.
See attached screenshot:

The two preview views always show same video clip, I would like to configure it to display one of the channels each as described in the documentation step 3.

I would expect the documentation for MultiCam editing to be more precise on how to do step 3 "Add a viewer region for every input channel and to improve the performance use proxies."

Exact steps for others to reproduce the error
Follow the Workflow described in official multicam documentation: https://docs.blender.org/manual/en/2.93/video_editing/sequencer/strips/effects/multicam.html

After some more search, I finally found the documentation for Sidebar: https://docs.blender.org/manual/en/2.93/video_editing/preview/sidebar.html

I Found Channel selector then via:

First enable Sidebar via View -> Sidebar
Then in Sidebar -> Click View -> Channel
There enter the channel number you want to view (0 = result, 1,2,3,... select channel)

So I think the documentation needs updating, as this is not documented in MultiCam Documentation https://docs.blender.org/manual/en/2.93/video_editing/sequencer/strips/effects/multicam.html
I expect a reference there to https://docs.blender.org/manual/en/2.93/video_editing/preview/sidebar.html to make this more easy to be found.

How would this UI solution work for you? https://developer.blender.org/D10521

Hi, Thanks for the reply, This PR of yours quite directly addresses my problem by making the workflow very intuitive.
In this case documentation would be not so important as it is in the current very hidden implementation :)
