A GPU-accelerated cross-platform terminal multiplexer written in Rust

Would someone be able to elaborate on the multiplexer feature? [1]. It appears like it's possible to use a single connection over SSH to spawn multiple terminals, sort of like tmux/etc?

It is pretty weird to me that there is no comparison with screen and tmux prominently displayed.
