@iconoclast,
I think what you mean can be explained by seeing the seperation between the 'objective' vision on things-in-themselves and the fact that those objective visions are still bound to subjective standing. A thought-object may (forgetting all the difficulties for a moment) be perfectly objective, it is still objective from a (subjective) human standing. All quantifications are things-in-themselves in their own right, because in actuality seperations can exist. There exist more than one things-in-themselves. The intent of an act is in that sense a subjective principle because it is 'vested' in a thing-in-itself, while the act-in-itself can be seen seperate from its quantification. So, in that sense intent is potentiality, but because it is 'vested' in a quantified thing-in-itself it also quantifies into certain states of that thing-in-itself: acts.
What you are referring to is explained by the seperation of that which is a priori and cognition I think. Cognition taking the place of the actuality and that which is a priori the place of potentiality. While one compares any and all thoughts to that which is a priori what quantifies in actuality is always 'shaped' by the actuality in the same way that a certain intent can be expressed in multiple ways. The way it is expressed is up to the subjective (knowledge).
I hope this is clear because I find my words sadly lacking in this matter. I think this can be best explained by the way new knowledge is gained though. It is clear there that some potentiality necessarily is present while otherwise one might be inclined to think that only actuality exists. As with all forms of creation, it simply won't fit into the 'flat' world model.
What I mean to express here is that potentiality quantifies into things-in-themselves (actuality) while things-in-themselves (noumena) can be viewed subjectively (phenomena) by things-in-themselves. People call subjectively that which is deformed by the workings of the mind, while in reality all thoughts, even objective ones, take place in a subject....
