It would be useful to link to the same file in different ways. On top of the regular [[File Name|Other Name to Display]] notation, it would be great to have some kind of aliasing.
For example: [[Economics]] and [[economics]] would link to the same file without the need to add the extra “|Other Name” thing. Another example: [[GTD]] and [[Getting Things Done]].
The benefit of using aliasing is related to consistency. Users relying on bcklinks and unlinked references would benefit greatly from this feature/plugin.
