To Juhis: Click on the rotate button to make it active. (see to the right in the picture). Click on shift while you rotate the object. Doesn't work on everything. If not - you can add these lines in the config (make tabs to next column):

rotate (tab, tab tab...) 1
rotate-yz-range (tab,tab....) -180,180

And that's it! You can change 180 to 90 or whatever you want the objects gradient.
