Do Windows (3D model, Main, trackpad QT) also need to be done?

Issue found in MVVM rework, but not initial.

• ~~Layout, gyro tab, joystick has left and right pad as options in the dropdown, these are not present in the main branch~~
• ~~CPU Core count initially shows double values (16 for 8), after moving the slider it's OK again~~
• Error: System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=Toggle_UniversalMotion'. BindingExpression:Path=IsOn; DataItem=null; target element is 'Grid' (Name=''); target property is 'IsEnabled' (type 'Boolean')

Minor notes, found during MVVM testing, not specifically MVVM related.

• Suspender read only DPI and fullscreel optimization info, remove?
• Profile, layout, buttons, disabled buttons still have a dropdown
• Endless amount of button extra's, perhaps limit to 5?
