Custom Buttons per customer
Customers may add their own Buttons for several reasons, eg. Link to the CMS Administration.
Therefore i suggest the possibility to create custom buttons on a per customer base.

The usage scenarion is quite simple: Have important links in one place. Let's say, the customer has a CMS like Workdpress installed. A custom button can link to the Administration of the CMS.
We run Lucee (CFML Engine) on some servers, which can be administrated on a per customer or site base. Therefore a link can help.
Expected Benefits: Make the life of the customers easy as possible ;-)
