I'm not sure which milestone I should assign to this wish, so I'll drop it in 1.04. ;)

oh, you can already do that "using "Textile" formatting (Hypertext Links)":http://hobix.com/textile/ in your entry (& notes).

This would work with files also, but it depends on the browser how to format the link.

For Firefox you would note something like

"open file":file:///c:/MyFiles/myFile.doc

which will turn into
[file:///c:/MyFiles/myFile.doc open file]

BTW: for users of Firefox (& Mozilla too AFAIK) there's a very helpful extension to automate the generation of links:

_"Make Link is an extension for Mozilla Firefox which adds a context menu item (Make Link) which allows the user to easily copy links to the clipboard in HTML, forum-code or simple "text (URL)" format. It also allows the user to create his or her own link types to use with the extension, and to modify or remove the default three. " "(SoylentRed.net | Projects | makelink)":http://www.soylentred.net/projects/?project=makelink_

Besides "Tracks" I have also configured it for the common formats, like xHTML, BBCode, Textile and even "Trac". To be honest: I am not willing to give that extension away again...

A project does have an associated link url. And the Markdown strategies discussed in this comment thread work, too. I'm going to mark this fixed.
