Allow Modals to Open / Reference other Modals

The Widget Inserter is a modal.
I'd like a way to be able to open the File browser to pick a file, or a folder, for the widget.

Currently, when you open a modal, it replaces the widget modal.
How should we deal with this?

We need to solve this.
Maybe we have a PAGE CHANGE when a modal is loaded.
This means the widget or module needs to know if it was in a modal or not.
If not, its going to be messy.

Loading a model from the editor is easier... not sure the best approach.
We need to do something, just need to think and discuss more.
