[Wish List]

Yes - the CAMERA viewport is linked to the camera(s) placed on the map -

The default CAMERA view - would be exactly what the 'Run Game'  view produces.

The camera is not linked to the viewport but rather is an independent  'object' -

 

If the 'camera object ' is rotated  - the CAMERA viewport rotates - yet the models retain their position 'in space' as well as in the other viewports.

[Wish List]

1.  Change: Appearance Tab - 'Hidden / False' to 'Visible / True'.

2. Add a Dedicated selector tool - with Pointer Cursor.

3. Add CAMERA to viewport options.

4. In 3d Perspective Viewport - Pivot on Selected item.

5. Change Default Viewports to include FRONT in place of BACK.
