Niri can even do one better: if you configure a keybind for the move-workspace-to-monitor-next or -prev actions you can move entire spaces between monitors, with wrap around. You can do the same for a column of windows (by default an individual window, but you can stack windows such that only one is visible in a group or that they're all visible in rows). I'll usually split my chat/monitoring spaces from my active development ones so I can passively refer back to them whilst working on an active task.

Niri offers a wonderful workflow; it really is an excellent piece of software.
