I went under the plugins tab and then The Featured tab and installed the "PHP Development Tools (PDT)" plugin. But whenever I go to create new, PHP is not listed there, so I click on "Other" and I expand the PHP folder and select the "PHP File" and it says, "Source Folder" then an error in the top right corner says, "Folder must be specified". How can I "specify" a folder or create a PHP file a different way then what I was doing, in Aptana Studio 2.0?
