I like them to the right – due to the fact that I don’t have to zigzag my mouse to select tab then ithe item.. but more: direct move to tab, select, move to item in same direction (moving left).
Though I have never had this system in experience because most systems have them always “out of the way”.
I do also like the fact that I immediately know what tab I’m in on mouse over instead of having to glance to the side on the Left to take note of whatever panel I’m in.
