Usability

Welcome. Sorry for my English.
1) It is convenient when one window you can open multiple projects.

2) In netbeansy when the project is created, you can choose which files and directories that need to be loaded.

/project/core
/project/templates
     /project/templates/mytemplates
/project/module
     /project/module/mymodule
/project/manypictures

For example, I choose these directories:
/project/templates/mytemplates and  /project/module/mymodule

because I do not need pictures, the total size of which more than 500Mb

This prevents the switch from NetBeans on PhpStorm
