[Feature] A visualization thats a mix of wall and grid

Is your feature request related to a problem? Please describe.
No huge problem, i just wished there was a view that was like wall in that all you see are videos, no text, but like grid because I want to see cover images for each video.

Describe the solution you'd like
What I would want is for a way for the wall view to not auto-play videos, but instead fill the screen with each videos cover image, but play the video if I hover.

it would be great to have this option I have slowdown when all the videos start playing in wall mode

I would still sometimes want to play all the videos on the wall, or stop them from playing and switch back to just showing cover images and only playing videos on hover.
