When I compare widgets provided by 'Subscribe by email'

Hello,

When I compare widgets provided by 'Subscribe by email' and 'e-Newsletter' I find the widget provided by 'e-Newsletter' much better as it provides ability to add text above the subscription box, provides number of subscribers. These functionalities are missing in widget provided by 'Subscribe by email'

How can these be enabled for this plugin? I would like to put widget for subscribe by email.
