Niri works fine on multiple screens, you can configure it pretty well. AFAIK it does not let you drag whole workspaces onto a screen – each screen has its own scroll of windows and set of workspaces, and you can move windows between them, but not move whole workspaces.

Definitely entirely LLM-generated with minimal review. The “docs” are literally just the LLM “plans”.
Unfortunate, it’s a nice idea (albeit one that makes more sense on desktop, and for most fields only pulling from their respective arXiv is more or less useless).
