Joomla Integration

Hi,

I am new to PHPStorm and super happy with it. I have a project that is connected to my local Joomla! 4 installation and happily working on my project while trying to learn more about what the IDE can do for me.

I am, however, not sure that I am  properly configured to be using the Joomla Plugin. I tried to define this as a Joomla project and recall some error flashed across the screen, but then I'm working with the IDE no problem. The software does seem to be aware of Text::_( and HTMLHelper::_( references, but there is no indication of automatically detecting the database connection.

My questions are:

1. How can I tell if this is a Joomla! project in PHP Storm. I cannot seem to find project properties.
2. Can Joomla aware PHP Storm be in any way configured to work on a specific component? In other words show me issues with my files in: 
   a) /administrator/component/com_mycomponent 
   b) /component/com_mycomponent 
   c) /api/component/com_mycomponent  AND
   d) /media/com_mycomponent 
   
   But not show me deprecated warnings and such from elsewhere in Joomla!?
