 * I want to change slightly content of excerpt component panel (i want to add a
   counter). It works by simply adding a script to the post.php page. But when I
   then click e.g. to editor, than the right panel switch from Post to Block and
   when I go back to Post panel, it is whole reinitialised so again without my changes.
   
   Is there any way how can i run my script always when that component panel is 
   generated? (e.g. catch some event)thanks

 * You would have to write an extension for the Block Editor to customize this component.
   Only then it will be displayed in the editor again and again.
 * Starting point for this would be the developer manual here: [https://developer.wordpress.org/block-editor/](https://developer.wordpress.org/block-editor/)
 * I guess there should be a filter for this, but I couldn’t find it. Maybe a question
   about your request will help here: [https://github.com/WordPress/gutenberg/issues](https://github.com/WordPress/gutenberg/issues)
