Hi @Karlek,
For actions and components you can see where they are used.
Actions have this for a longer time already and it moved location a little bit over time. With the newest versions you can always find it all the way to the right in the action menu:

We can see that it is being used in a form component for it’s
Data
setting and it’s being used by itself in the errorToast
field.
Since v3.108 components also have a view where you can see their usage. To open that view, click on the hook symbol next to the components title
This shows you the components usage in a similar fashion like the actions view.
For both components and actions you can click on the field the data is being used in, which is the yellow/orange text with the purple background color. That will bring you to the exact place you used that component or action.
