Tasks should be able to be hyperlinked to another project tasks.

Description
I like breaking up projects into nice easy to see sections and like using master - sub projects.
Given that Planner uses an XML file format it would be relatively easy to make a task that is just a hyperlink reference to another planner file task.
That file could either be remote (http://) or local (file:/// with regular URI conventions (for GNOME).
The updating is probably easy to set as an on-demand refresh of links - maybe some stale link checks (per-day).
The planner simply gets the remote document, parses it and picks out the relevant task (or tasks) and then sets itself up with those details.
I'd also expect a picker to allow you to choose a remote task.
