These 360 videos need better view angle controls. Rather than just replicating the arrow keys, the "D-pad" in the upper left corner should be replaced with an "analog stick". That is, the rotational velocity should be proportional to the distance from the center of the stick to where I click (and hold), with a continuous choice of angle.
I thought the same until I watched a 360 4k music video on my iPhone in the YouTube app and realized the desktop/laptop browser experience is irrelevant for this application.
No idea. Actually the way this works in some players is a mouse drag acts as an analog stick, moving with proportionate speed the further you drag from the start. That's how QuickTime VR worked two decades ago and it seems we've regressed since.
That said, mobile and touch is a better platform for this experience, and using touch gestures the "globe spinning" behavior works better.
Is there a reason this isn't done? Seems obvious.
