So, I programmed the water with the "clear everything" function that everybody is going to start with. 

Now, I have a giant flask of water. But I also want a good nights sleep, a Cheese Burger, and lots of other things. 

Can I continually program the water with other elements (Chakra Cleanses, Ferraris, Relationships) or would that muddle it up?

It would be easier to send the functions to "Quantum Field" as opposed to a given medium. The Mediums are limited (i can only drink so much water)

Other than this, does Imagi really perform better than a Vogel Crystal? Is it just intent with a nice interface to get people to be more mindful in terms of their intentions and how they always immediately manifest?

Not that this is a bad thing in any way, of course. If Imagi replaced public schooling, wellLots of Conscious Creators would we have.
