Is it possible to create a custom navigation toolbar with NControl?

[Emasoft]

The current navigation toolbar of Xamarin.Forms has some serious limitations.

It lacks options to:

• customize Icon positions
• add badge notification counts
• use colored icons
• use background gradients or images
• add custom back and forward arrows buttons
• use custom fonts in the bar title
• use attributed strings for localization and formatting
• change the color of the icons when receive notifications
• drop shadows below the primary and the secondary bar
• use the secondary bar like a tab bar with animated underline horizontal movement when changing tabs

Is it possible to create a custom navigation toolbar with NControl, so that one can easily add all those features in a cross platform way? A basic template of such control would be awesome.
