+*** org-attach
+=org-attach= is useful to attach reference material to org files. This can be reference images, data or other files. A special link type is available for attached files: ~[[attachment:file]]~.
+
+- Inheritance :: While inheritance for attachments sounds useful, so subheadings can access their parents attachments, I find that the current implementation (Org 9.3.1) instead of inheriting just sets the attachment dir of all children to that of the parent. So for now I decided not to use it.
+- Attachment Folder :: While I do not like the default double nested
+  folder structure it creates, I also do not want to set an individual
+  =DIR= property for all headings I want to attach something to.
+  Instead I define a new function to use the uuid directly as the
+  folder name.
