This is a feature request for RM Bridge

1. When the main graphic windows show the model, the right-click menu is enabled for the the side graphic window

Please refer to attached 1.png.

2. But when the main graphic windows does NOT show the model, the right-click menu is also disabled for the the side graphic window

Please refer to attached 2.png.

3. The reason I want to enable the right-click menu for the the side graphic window is: I can use right-click menu to control the model view when I edit the model in the main window.
