Yeah right now, the dependence on title matching makes it pretty limited. Especially when using date-based UUIDs as titles instead of names.
There is no feature yet. Maybe this will be addressed with Note Aliases or by the plugin API, or by a future feature. Or maybe you can think of a way of using tags or MOC pages to conceptually link things.
It would be great if link suggestions could have some kind of a fuzzier match. It would perhaps have some danger of matching too often, and creating noise. How would you distinguish between meaningful words like “usability” and common words like “made”, “three”, or “things”, as examples?
