Thanks for the suggestion. It’s an ingenious solution, although it does not fit into my current workflow.
I use tags and groups to represent “weak relations” only: A group of documents are all related to one project. Documents with the same tag are all in some ways related to the same topic. For “strong relations”, such as that between bananas are sweet and I like bananas, I prefer using an item link with context in either document. I like being able to (1) find every single “strong relation” of a document in one right-side pane, and (2) retrieve context either directly, or through a custom-made script.
Anyway, thanks again for mentioning this possibility. Learned something today Image may be NSFW.
Clik here to view.
