  * Independent models for each button providing custom options through
    method overriding.
  * Section separation of control panel entries.
  * Extendable sections and entries for plugins through proper hotspots.
  * Quick section and entry search on the control panel view.
  * Use of font-awesome icons instead of obsolete tango icons.
  * Reorganization of pages making them smaller and more concise.
