Removing White Boxes and Minimizing Bottom Box

Hello,

How do I remove the white little boxes above camera and properties box? Is there anyway to reset the the whole thing back to original setting. I Uninstaller and reinstalled and it brought back just how I left it. I was messing around and somehow made these little errors. Also, how do I minimize the timeliness box to the original size? The box is so large, you cannot tap on the end and resize. 

Thank,

Gary
