Hyperlinks

FreeMind supports having one hyperlink per node, linking to web pages, mail addresses, and to local files.

Implementation

Making hyperlinks work fine on all the supported platforms including Microsoft Windows, Max OS X and Linux is technically tricky, requiring dedicated code for each group of platforms.
