It's quite simple -when i use my own models and libraries i get extra autocomplete options that makes findings a needed opinion more difficult, and it just unnecessary garbage.
It is without making model.php and controller.php are marked as plain text
(i got only what i need)

It is when they are marked as a plain text file
(i get a lot of garbage results)

Is there a way to improve it?
Of course without marking model.php and controller.php as plain text standard models doesn't work properly (such as DB and so son)
