A simple window controls question

The harder question is why they did it.

I have been setting up a new iMac this afternoon for a very non-technical friend. I have come home amazingly frustrated from trying to use her machine to do simple web browsing and software installation. The main issue I had was with the windows.

OSX used to have three buttons to control the window size: minimize, maximize and justrightsize or whatever the third button is called. This has changed, I think in 10.7 from what I can see. Now there is a sort of arrow in the upper right corner. You press it and the window is full screen. The window control that you just used is GONE.

How is one supposed to use this very poor design decision? I really doubt Command-Shift-F is what Apple intended people to do. I did find the bit at the top of the screen where it looked like I could resize (or at least minimize) the window from the pulldown menu, but it didn't do anything.

What were they thinking?

Thanks for the help,
Steve

Can someone please tell me how to work these silly windows? I think this is really an elementary question that I'm embarrassed to ask, but 158 views and no response?

Thanks,
Steve

Thank you Dark Dragoon, exactly what I needed.

One time years ago I was trying to make emacs work. We found a comment concerning / or \ for paths that applies here:
"whoever did this had better not admit it".

Thanks again,
Steve
