That sounds like a very handy bonus, actually. And there may be other reasons of convenience as well. Syphon looks very useful from my own unpracticed perspective.
It should be understood though that CamTwist does indeed need to actually have the quartz compositions in it's own default Effects folder before they can be selected to be loaded. There is also an alternate location that can be used if it's desired to keep custom compositions separated from the default CamTwist effects, but it has to be one or the other ... CamTwist can't directly load externally located quartz compositions. Syphon (or a screen grab) would have to be used in that circumstance. Just to be clear in that regard.
