Focus mode for video conferences

[alangecker]

Is your suggestion related to a problem? Please describe.

In video conferences the space for widgets is quite small, especially on lower desktop screen resolutions.
Widgets like jitsi offers a fullscreen button, but this hides the chat, which is required for some facilitating methods.

Describe the solution you'd like.

For rooms containing video conference widgets there could be a button offered, which switches the layout to a minimized one:

• Hidden sidebars (LeftPanel, RightPanel)
• Hidden header
• Hidden rarely used controls
• Vertical aligned chat (less unused white space)

Proposal: Minimized Layout

Normal Layout for comparison

Additional context

This was already implemented in our Element fork in a quite hacky way. But hope to have something like this at some point upstream in an beautiful way :)
