I'm currently testing the new PhpStorm 2.0 (96-1061), and my first big problem was how to configure the External Libraries. I tried to right-click it (like in eclipse) to configure the paths, but there is no possibility to configure them. So after 10 minutes of searching the menu and settings I found "PHP Home" and after settings this to my php installation and clicking "update include paths" i got my libraries working.
Would it make sense to have an extry in the context-menu of the "External Libraries" to "configure" them? That would make it easier to find this setting.
