I did not see an option for this, but upon completing RIP (successful) it would be great to eject the disc automatically. I have found that when you hit close on the pop up it wants to start reading the disc again then takes a while to scan before it wants to eject. It doesn't seem like a big deal until you're doing tons of movies!
The other benefit is, if you are working on something else while waiting it would be a good sign that it is done.
