Currently Lemmy has a lot of blank space on left and right when viewed on a 16:9 PC monitor.
(I assume that it’s even worse on wider screens) It would be very nice to have a Lemmy theme that uses all of the available screen space.

I am convinced that userstyle would be the best first step. It would allow us to iterate and experiment. That way we can come up with a good draft before we ask developers to implement it.

We should open an issue in Lemmy-ui repo about this though.
