Great!

In the past, we've kept forward compatibility but not backwards, which I
think is fine if it's hard to avoid breakage. 

In this case though, it should be easy to just add the initial property
as "#IMPLIED" in the DTD which makes it not required, and then make sure
that we can handle loading files that doesn't have that property. The
old versions should work out of the box if we do it that way. 

We must not forget to add load/save code to the database backend and
maybe the HTML export as well.

Good catch, looks fine! I'll commit it for you.

That would indeed be a good addition, even for only one task at a time.

One thing that would help usability in this area is an icon column to
the left where we can flag different things like "has a note", "has a
constraint of type foo", etc. Also having the ability to set constraints
in the task dialog should be good.

Thanks!
