[Planner Dev] Remembering Tree State

[Robert Woolley <planner-dev robertwoolley com>]

Hi,

	Planner is such a great tool.  I'm hoping to contribute at some point
in the future, but in the meantime I have a suggestion:

	I find it awkward when I open a new file and have to open and close
different branches of the task tree.  Would it be possible to store the
state of the branches inside the planner file?

Cheers,
Rob
