When opening one specific file (ProductController.php), i do have a lot of tabs beneath Editor and Preview tabs -> see screenshot

They seem to come from some filtering i canceled (because it took too long) i did before. I don´t even know anymore what command i used to start this filtering

But how to i get rid of the tabs now - i don´t need them anymore?
Clicking on these tabs starts the filtering again. But there is no way to close them.

thanks

if your project uses one of frameworks supported by PhpED and you enabled it in project settings, IDE tracks dependencies like (Controller->Views) and shows them in those tabs below.
If you don't want to have this tracking, just disable framework in the project settings.
