What kind of button would you want to press?

really, cause that's exactly what button I look for when I'm in an IDE trying to figure out how to run a project. I'm sitting here looking at intellij which has a 'play' button for running code.

I just checked Eclipse: Green circle with a white, right-pointing triangle. Then I checked Netbeans: Green right-pointing triangle. Both of these are unmistakable icons for 'play'. Edit: I even googled for screenshots of Visual Studio...green right-facing triangle.

Could there be a more universal idiom in the world of IDEs?

Me thinks you haven't been programming long if you don't know what the green triangle does. It's been a "play button" for over a decade.

Guys, try reading his post: "When I want to build my project I do not want to press a play button."

He said BUILD, not RUN. A Play button is to build and RUN the project. I agree with his objection: There's no Build button in the UI.

And even worse is the width of the combined drop-down list for configurations. There's a vast expanse of empty space in the (now non-customizable) toolbar, and they made this control SMALLER. The information it should be providing is cut off in all cases, even with short project names. I try to be sympathetic to the Xcode team's tasks, but this is idiotic.
