[Feature]: Allow further cover card customization

[MXNPD]

Is your feature request related to a problem?

No, just a QOL change and to allow further customization of the card.

Describe the solution you'd like

Being able to change the icon color background on the cover card when in the open and closed state. IE if cover is closed, display red, when opening/closing display yellow, and when open display green (and allow customization of this to users). And bring this same type of functionality to the buttons, IE allow us to define a green button to open, and a red button to close and allow the user to change the mdi icons of the open and close buttons respectively based on their requirements.
