In my current, The Archive based, Zettelkasten, I use [[UID]] for links between my notes. When I use the Markdown Importer in Obsidian, these links can be converted to either [[UID File Name]] or [[UID File Name | File Name]].
I would love to see a third option: [[UID File Name | UID]].
Why?
Because in my current notes I often like like this
[[UID]] File Name
or
Some facts in text and a reference to where I can read more about them [[UID]] and then my thoughts about that.
