TWO Rendering Wishes ...

1 . Pause Render Button - Sometimes when I'm rendering, my computer is barely functional (and I have 8 cores!), so it would be nice to Pause the render so I can actually write an email or something .... this is especially true for a long render

2. Background Render Option - Like above, when my computer is at it's knees, it would be nice to enable the Background Render Option, so I can render throughout the day, while still getting work done. So when I'm in Photoshop, the FF render would be lower priority on my CPUs ... and when I go eat lunch, the FF render would be a higher priority.

Is this something hard to implement?

thanks!
