Alinks and Beyound, other uses

Something came to mind as i was looking at the module which may expand its scope of use for hopefully very little coding

When you mouse over a 'String' you get the 'URL Title' read that as 'NOTE'

If it were possible to not enter a 'URL', and when no URL is present the word does not get underlined, but the link icon appears (or preferably a different one in these cases) you have a 'String' that links to a 'NOTE' (URL title) you now have a very simple Glossary module

Whether this should be a sepearate module or part of the same is a different matter
