Allow component preview on editor.

The editor currently lacks the capability for users to test dynamic components within it.

Implementing a "Preview" mode, accessible through a checkbox (near the delete & duplicate btns), could significantly enhance usability. In this mode, users wouldn't be able to reposition the component but could interact with its functionalities.

Such a feature would game changer the editor by enabling the creation and testing of dynamic, editable components directly within the editor.

For instance, users could adjust the settings of a "tabs" component via the sidebar and immediately experience its behavior in the editor, facilitated by this proposed checkbox.

We did originally have "Alt" as a hotkey to enable direct interaction, but it was undocumented and got removed at some point.

Keen to explore this again.
