You can move items to balance things a bit better and also choose items to add or delete.

Yes that is what i would like Thanks
I also have a question about Safari using my 2015 MacBook Pro. When I expand Safari using the green button to make it use the entire screen. Once it's full expanded and then I go to open one of my bookmarks say for instance this website forum, the aspect ratio goes off, meaning to see the entire content I would have to scroll over to th right to see the content. Then if I X out of the expanded safari so it's not full screen and then quickly toggle back to full screen then the content wraps correctly on full screen.
It's not just this site it happens to a lot of my bookmarks in Safari. If I'm already in expanded view and changed websites sometimes the content doesn't wrap while in expanded mode but if I toggle expanded off and then on again it wraps it correctly. It's driving me crazy and don't know how to fix it except just toggle off and on.
As mentioned before, you can't directly move the search bar itself. It's position is ,mainly dictated by the arrangement of your other buttons either side of it.
So if you want to move the search bar a bit over to the left, right click on the bar, choose "Customize Toolbar.." and drag one or more of your buttons from the left hand side of the bar to the right side.
Or add an extra button or two to the right hand side.
You can also use the "Flexible Space" additions in the Customize menu to move it left or right without the need for additional buttons cluttering up your bar. As you move the buttons about you'll see the search bar moves left and right. When it's where you want it, stop moving buttons, your job is done.
Perhaps you started a new post for this. I've tried to get Safari to do what you say your MBP does and I cannot. Even if I make the font enormous, it still wraps whether I am in full screen or not. What system are you using? What version of Safari. I'm using Sierra 10.12.3 and Safari 10.0.3
