Comment 1 for bug 538574

I agree the buttons should have tooltips, especially because you guessed all the functions wrong, so that's not really user friendly indeed. The tooltips are added, I hope they will make some things clear. The buttons are actually from stock, so I don't understand why they didn't have any tooltips in the first place.
I currently believe the order is fairly okay, but let me know what you think. I will also grey out the buttons that don't do anything when the list is still empty.
Thanks again!
