How to enable the Customize Design menu item (widget editing) for editor level users.

I would like to enable the Customize Design menu item (widget editing) for editor level users.

Using the Manage Menu Items addon, this item is checked under Show or hide menu items, but does not appear in the editor level menu.

Should I be using a user role scoping plugin to achieve this? If so, which is most compatible with Easy Blogging?

Or is there another way?

Thank you.
