Maven Projects Side Bar

Question

I've just installed the community edition v13. What has happened to the side bar to the right which had the maven projects. With one click it would display the maven projects. When I go to View -> Tool Windows -> Maven Projects it displays but when I hide it, it completely disappears. It didn't do this in version 12. It's annoying to keep going to the top menu bar. Any ideas on how to get it back?

Answer 1

In Idea 13, in left-right part are by default invisible(to not use place). Click on showed button to go to previous style.
