UI and mouse scrolling question

[GT_OKEZ]

How do I change the size of my UI to be bigger or smaller?

How do I set up my mouse to scroll the map without holding down left click?

Thanks

There is an option to enable scrolling the map if the mouse cursor is near the edge, rather than having to click-and-drag. I am struggling with it a bit, though, as it starts doing so close enough to the edge that trying to access some of the menus starts the scrolling.

Has anyone been able to adjust the size of their user interface?
