Currently, a modal is always opened in the middle of the screen.
In several use cases, we would like to open a modal by clicking a button - and the modal should be placed beside or below the clicked button.
So a improvement would be to anchor the model to a specific component of the page. I could imagine that the developer can select the component to which the modal shall be anchored, plus the orientaion (left, right, above, below). Other option would be to use a class name as component reference.
