How do I get my button for several tabs back in Chrome?

[AC Question]

When I open chrome and want to open several tabs and switch between them, I have to use the "tab touch-button" on my samsung S5 to access, but then it shows all my active apps and programs... Om my last chrome (befor the 5.0-update) I had a button in the top right corner in the browser where I could see my other tabs in Chrome...
