Rebranding & Dashboard

This plugin works very well but can not really realize a rebranding of the CMS!

I’m thinking of the dashboard and the panel “Right now” where appears clearly written that you are using WordPress, the name of the theme and how many widgets are active.

I also tried with different plug-ins dedicated to manage the Dashboard but none solves this problem. The panel “Right now” is very useful and should not disappear but this information is typical of WordPress and I think that should not be there in a rebranded installation.

Can you suggest a solution?

Thank you very much.
