I also really like how you can click to change tabs and languages, it's intuitive. Keeping in line with that, perhaps a click on the line and column info should launch the "Go to line" window. Not that i'd ever use it, just to get that intuitive feeling. Also, while others ... are in the tab settings when you click on a window, it does not appear in the drop-down menu, this is inconsistent behaviour and therefore bad :)
