Very nice project! It's really very good! Thanks for sharing it!
Initial impression is this software is full of bugs. Drag and drop a PHP file to it, it throws an error. The PHP file is opened but not displayed. You cannot dismiss pop-out tool panels without closing them, as there is nothing to take focus away. After these failures, I simply uninstalled it. Granted, getting further into the editor may provide a less buggy experience, but because the PHP file wasn't even displayed, I couldn't do anything.
