The Multicam strip is one of those functions in the VSE which is quite powerful, but the UI could be more user friendly. This is an attempt to do so.

Cut was previously renamed to "Split", but since the buttons both can do a split when the playhead is over a selected strip and change channel of the selected strip when the playhead isn't over the strip, I find using the word "Switch" more suitable. This word is in line with the industry term "Camera Switching"
Currently there isn't any selection option in the preview and having many previews open leaves little room for having the sidebar open to display the channel number previewed.
So, when the preview is a channel 0(view the result of all channels), buttons to switch between all channels gets exposed and when the channel number is specific one, that channel number will be exposed and a switch button will be added.
These changes opens up for this much more user friendly editing workflow:

Small fixes:
- Switch selector buttons are aligned in 2.8+ style in the panel.
- In Multicam strips the name overlay "Channel: 1" will be cropped from the right, so this has been changed to "1. channel", in order to perserve the number for as small strips as possible.
A note: using 25% proxies in the source previews and 75% proxy in the result preview allows for realtime playback of 720p footage(not final UI in this video): https://www.youtube.com/watch?v=H9j8B3h8GSQ
