Please add keyboard shortcuts to cycle forward and backward through all existing cameras in a scene. This would eliminate the need to go through the outdated and cumbersome menus, which currently require multiple clicks to access each camera. It would be a huge time saver for users and, in my opinion, relatively simple to implement.
Additionally, I suggest improving the current camera and light selection menu system. When there are more than 10 cameras, the interface switches to a two-level nested menu, which is inefficient and slows down workflow. Replacing this with a single, unified selection system would provide an immediate sense of ergonomic improvement for all users.
