Expand video boxes to use all screen in grid

I’ve spent a fair bit of time configuring Jitsi on an Ubuntu instance, however I cannot see anywhere I can change the video box sizes within the grid to use all of the screen space. I don’t particularly care for the grey padded spacing on all the sides of the video boxes.

See the attached as an example of what I’m trying to achieve.

Many thanks, Andrew.

Just a gentle bump along.

No-one is keen to see edge to edge Jitsi? Or we don’t know how to do it? Or we don’t think it can be done?
