Be able to link notes to each other, similar to a wiki.

Navigate directly from one note to another via links, like a wiki.
It would be nice if you could alias the name of the link for the note. That is, like a web site, the display text can be different from the actual link url.
There should be some simple way to be sure you are getting the correct note name in the link when you are creating it. For example, as you type, dynamically display a list of matching notes to pick from.
Renaming a note should rename all links to that note.
