In a previous beta iteration, there was an up/down arrow icon for each camera group that would expand to show thumbnails of each camera without the need to load the live multi-cam view first. The user could then go directly to a single camera view, bypassing the multi-view.
This topic is asking for this feature to be restored. I’d suggest a +/- icon instead of the up/down arrow.
Adding this feature would also allow the ability to display some camera status data in the blank space to the right of each thumbnail, such as on/off status, notification on/off, etc.
