Moving moodboard around

It would be really helpful and much easier to navigate the mood board area if you could zoom in and out using the central roller on a mouse scrolling up & down, and being able to move the canvas around, without selecting an item on the board by holding down the central mouse roller and moving around.

Or, since currently you can move the canvas by holding down the space bar, if you could zoom in & out with the mouse roller while holding down the space bar, that would be another way to make it somewhat easier. Having to go up to the left corner to zoom is just cumbersome when creating fine details and it would be nice to have the ability to jump in size at less than 10% increments.
