You can resize windows in the game. Put your mouse over the very edge, right on the line, on the left or right side of the window until you see a horizontal 2 way arrow (looks like this: <->). Hold the left mouse button and drag it to stretch the window. You can also stretch it vertically as well. Stretch the window until you have all tabs on the top shown and there is no need to scroll left/right anymore.
I went to the Delta Quadrant and the Kazon stole my stupid T-shirt. Also, my pet hamster that died when I was a kid is now a Kobali.
