In most cases I would say you are right Juju---except for these, I think.
Chuck V.'s plugins are some of the best in the industry, and in particular,
the door & window tool. Its parametric settings are better than anything I can produce in
either Archicad or Vectorworks, and it has alone saved me countless hours to create
very complex windows, doors, and door systems.
Of course, if I could wave a magic wand, they would be perpetual.
Oh, well......
Cheers.
