When I got bored a little while ago, i was fixing my home screen and after long pressing and holding for a second after it vibrated and u could drag it then letting go I got this weird looking thing and saw I could re-size icons. This mostly works with all icons but some cant go too small but it just takes over a certain amount of pixels for the icon to occupy. When i was done with how I wanted it, I just hit the back button and it stayed that size.
