Re: FW: [RFC] Link-type for attachments, more attach options

["Gustav Wikström" <gustav@whil.se>]

Hi Ihor,

I'm not sure I follow your suggestion regarding changing the implementation. But anyhow I don't think the implementation is heavy and at risk of cumbersome code duplication. My opinion ofc 😊

I like the idea of a function that would symbolically links folders from "ID"-folder structure to a hierarchy-folder structure, based on the name and path of the org-file  and its headings containing the links. I probably wouldn't use it much myself though. Not until org-mode starts working better with multiple files, allowing us to more easily define "org-mode libraries".
