Customizable Dashboards

• Supported custom list of Widgets for Tabs in Dashboard with help of verbose_level and include_widgets parameters
• Added parameter verbose_level: 0 - to create a Tab with the shortest list of Widgets, 1 - to create a full Tab
• Added parameter include_widgets : ["Widget Name 1", "Widget Name 2", etc]. This parameter overwrites verbose_level (if both are specified) and allows to set a custom list of Widgets
• Added Tab.list_widgets() method to list all the available Widgets for the current Tab
• Created Options entity to specify Widgets and Tabs customisable settings
• Created ColumnMapping entity instead column_mapping python dictionary
