Thanks, but could you clarify which extension to move for Gnome? native window placement is AFAIK just for the overview.

Which extensions do I need?

Ah, sorry to read - I like the idea of Bcachefs and would have been happy to have it ready for production eventually.

OTOH it seems the recent years I read more about the drama about Bcachefs commits to the kernel, than about any technical parts of Bcachefs.
