Not used global

When you delete a komponent than use a specific global, that global is garbage since you deleted his use. Can you add something to see a global is not used by no one?

This is planned, i need to create a "clean" button that will remove all unused globals

And selecting a global and show it to you where is it used (component+field)?

Thats more tricky

What about a warning when deleting an overlay the prompts you that it'll break a global setting? Yes or no to proceed with deletion.

Wondering if there are any updates on this
