Logic Exp 7 Question Options

[MoonDark]

Hi guys , I am very new to this software so I was wondering something.

when I open LE7 i get an untitled default document with the arrange window open... that arrange window shows many stuff, like the tracks window , a small mixer, The Midi small menu etc...

I created a new proyect and the arrange window only shows the tracks ... how can I make it to display everything ??

Thanks , and sorry for the silly question
