Ah, what about equivalent of treesitter/object grammar,~api[1] to group/relate/associate object(s). aka spatial versions of fold/roll-up. Perhaps also as way to interface visuals with other actions/devices[2].

Because it's y-combinator, perhaps emacs "note card(s)" for links related to object/group of objects further details.
