Without changing any of the xml code, there should be settings within the game that will allow you to change somethings around. You can increase the scroll speed of the camera if that would make things any easier, and you should also be able to change the UI from being set to "normal" to "large" (assuming that your monitor is able to accommodate the change, which it seems like it can).
Thanks. I had forgotten about the UI size setting. I't definitely a usable workaround, even though it does make the UI quite large even on medium setting.
Does changing .xml disable achievements? If anyone could pinpoint if it is possible to change only the minimap size in one of the xml files, that'd be great
