On the contrary, polygons have all the standard properties you would 
expect, including a points property which can be set to change the shape 
  programmatically.

The limitations cited in those Bugzilla entries focus exclusively on 
behaviors in the free-form interactions possible with the pointer tool. 
  For a project management app the primary diagram is usually a Gantt 
chart, for which using the pointer tool would be more free form than 
likely desirable.

I can think of no reason such specialized types of diagrams and charts 
as Gantt couldn't be made beautifully in Rev just as it is today.

And you could tie it in with a database, which would be especially 
useful for a networked muti-user version.  But if you just want a 
single-user version, the quantity of data is likely small enough (unless 
to intend to run a national renewable energy program from it, or 
something else on that scale) that you could store your data in user 
properties quite happily.

for some ideas on using a stackfile for structured data storage.
