Did you have a look at the documentation for Navigation and AppDrawer?
Which feature exactly are you missing? The AppDrawer can be placed both on the left and right side of the screen, the Navigation element always uses the left side as this is the default for the main Navigation on Android.
You can have a look at the Component Showcase demo that comes with the SampleLauncher of your Felgo installation. It shows how to use both Navigation and AppDrawer.
The resolution and theme menuBar is only shown for test builds on desktop by default.
When you do a publish build for releasing the app, it won’t be visible. You may also set the App::menuBarVPlayEnabled property to false.
If you wish to create a custom menu, you can overwrite the menuBar property, which App inherits from the ApplicationWindow base type.
Have multiple NavigationStacks with an initial page and only switch the visibility when another menu-item is chosen.
The second solution is similar to how the the Navigation type works. This allows to keep the state of each main page / stack. (E.g. when you push a sub-page on the first stack and then switch to other pages of the main menu the sub-page is still active on the first stack).
