iTerm has support for tiling terminal panes within a single window. You can drag any tab to subdivide a pane as much as you like.

It's handy for keeping "tail" or "watch" commands or similar visible — the same reasons people use tmux, tiling window managers, so on.

The UX isn't perfect, but it's useful enough that I've stuck with iTerm despite the lower performance (and bugs — it's pretty buggy, and the main author rarely seems to address Gitlab issues).

iTerm has other nice features. It can run without a title bar (saves space), it does cmd-click-to-open-file, and it has a lot of customization options. I don't really use most of the features; the tiling aspect is the main feature I rely on.

I love terminal panes. I'm not sure at this point what comes out of the box and what is custom configuration but I have keybindings for creating vertical and horizontal splits, and additional keybindings for navigating left/right/up/down.

My setup is to run MacVim on the left half of the monitor and then iTerm2 on the right half. iTerm is then split into generally three horizontal splits.
