Can you move ResourceDictionaries/SideBarResources.xaml to UserControls/SideBarControls.xaml?
Can you remove UserControls/Sidebar folder, which is not used anymore (that folder seems to be included in your initial PR incidentally)?

I don't really like having the eject button on the sidebar because when you have a lot of removable drives, it can quickly clutter the sidebar. So, I suggest implementing a button in the settings to enable or disable this functionality.
