Style of the navigation bar is not working well all the time (Questions on the styles options)

[loicparent]

Hello,

I'm trying to configure the plugin for my application.
First of all, the expected behavior is working fine but, I try to customize the render or the behavior and I have a few questions/notes:

1. By default, when I show the navigation bar, the viewport change (you can see the title is moving up). Is it possible to show the navigation bar with an overlay on the app and not by changing the viewport area? (something similar as the method .setTransparency() but with a background)

2. When I enable the transparency mode, it works fine at the init but, if I open the "App Switcher" and then go back to the app, the navigation bar is then visible with a default dark grey background. Is it possible to keep the navigation bar transparent?

3. Is it possible the use alpha color for the navigation bar? So, use the color mode (not the transparency mode) but with a percent of opacity?

Thanks for your help,
