yes and yes
i have a mod to make the window start out transparent which helps a lot, but higher resolution fixed that button issue for me. (i use 1280x1024)
there was also a tutorial on how to customize the location of the window as well, it relocated it to the bottom of the screen like it was in sh3. using the same info maybe you can figure out how to do something with the buttons but im guessing they probably need to be on top but maybe you can resize them.
here is the thread that explains it:
