Enhanced Brush Controls

One thing I would find super valuable would be enhanced brush controls in Photoshop. I know there are mixer brushes, but those don't achieve what I would like. 

I would love:

- Ability to have texture rotate and change size while drawing

- Customize how much a brush multiplies or other adjustments

- ability to add a smear type of function to brushes so that they smear in real time

- overall more control of outcome
