Search bar and theme

I don't like the search bar that it comes with. The box is too small, there is no autofill, it doesn't have the same tools as regular Google (i.e. maps, videos, etc.), and it automatically takes my cursor away from the actual toolbox and puts it in your search box. Also, could you make it to where it can use my actual Google Chrome theme as my background? I don't like all that beauty-nature-y stuff it has (I use my computer to get away from nature) and all the pictures I have are garbage.

I think I'm done ranting. Yeah.
