A development process should be comfortable. It means that you should have an editor or an IDE that allows you to express your thoughts in a fast and easy manner. Of course, the editor or the IDE requires fine-tuning. If you are working on a new extension for Plesk, I suggest to take a look at PhpStorm. It’s a great IDE by JetBrains for PHP-based projects. Good news are that PhpStorm has a 30-days trial and you can try it for free. Out of the box PhpStorm does not know anything about Plesk extensions. And we’ll try to do the development of Plesk extensions a little bit more comfortable.
